As a resource, allogenic blood has never been more in demand than it is today. Escalating elective surgery, shortages arising from a fall in supply, a lack of national blood transfusion services, policies, appropriate infrastructure, trained personnel, and financial resources to support the running of a voluntary nonremunerated donor transfusion service, and old and emerging threats of transfusion-transmitted infection, have all conspired to ensure that allogenic blood remains very much a vital but limited asset to healthcare delivery particularly in Sub-Saharan Africa. This is further aggravated by the predominance of family replacement and commercially remunerated blood donors, rather than regular benevolent, nonremunerated donors who give blood out of altruism. The demand for blood transfusion is high in Sub-Saharan Africa because of the high prevalence of anemia especially due to malaria and pregnancy-related complications. All stakeholders in blood transfusion have a significant challenge to apply the best available evidenced-based medical practices to the world-class management of this precious product in a bid to using blood more appropriately. Physicians in Sub-Saharan Africa must always keep in mind that the first and foremost strategy to avoid transfusion of allogenic blood is their thorough understanding of the pathophysiologic mechanisms involved in anemia and coagulopathy, and their thoughtful adherence to the evidenced-based good practices used in the developed world in a bid to potentially reduce the likelihood of allogenic blood transfusion in many patient groups. There is an urgent need to develop innovative ways to recruit and retain voluntary low-risk blood donors. Concerns about adverse effects of allogenic blood transfusion should prompt a review of transfusion practices and justify the need to search for transfusion alternatives to decrease or avoid the use of allogenic blood. These strategies should include the correction of anemia using pharmacological measures (use of antifibrinolytics to prevent bleeding and the use of erythropoietin and oral and intravenous iron to treat anemia) use of nonpharmacologic measures (preoperative autologous blood transfusion, perioperative red blood cell salvage and normothermia to reduce blood loss in surgical patients). All these strategies will help optimize the use of the limited blood stocks.

Voluntary blood donation is not satisfactory all over India. In India, about 55% of donation is through voluntary non-remunerated blood donors (VNRBD). However, about one third already motivated blood donors are deferred due to stringent screening criteria, either temporarily or permanently. The temporarily deferred donors could be a good source of blood donation after deferral period.
The present study is carried out to know retrieval of blood donors those who are deferred temporarily.
The present study is carried out in the Regional Blood Transfusion Centre of Western India. All donors screened as per the guideline and deferred donors are categorized as temporary and permanently deferred donors.
Materials and Methods:
From temporarily deferred donors, reason for deferral is considered. As per reason of deferral, time duration for recalling the donor is defined. Based on this, donor is called back to donate again.
Chi-square test is applied.
A total of 33% donors were deferred either temporarily or permanently. In the repeat donors (5.32%) deferral rate was significantly higher than first time (1.32%) donors. Significant female preponderance was observed (15.05% vs 2.51%). Majority of temporarily deferred donors were less than 40 years of age (80.80%), graduate (82.90%), from low income group (62.90%) and profession was service (48.10%).
Low hemoglobin (78.30%) was the most common reason of temporary deferral, both in first time and repeat donors (71.00%). Efforts to increase the hemoglobin in the repeat donors will improve the donor retention and overall blood safety can be increased.

Family/replacement donors still provide more than 45% of the blood collected in India. National AIDS Control Organization passed the guideline that family/friend donors should be considered as voluntary donors by the blood banks in India.
Materials and Methods:
We did a prospective analysis of Transfusion Transmitted Infections (TTI′s) on our family donors for the years 2009 and 2010 to compare the results and evaluate if family donors are as safe as voluntary donors.
The prevalence of Human Immunodeficiency Virus, Hepatitis B surface antigen, Hepatitis C Virus, and Anti-Treponema Palladium antibody was much higher in family donors in comparison to voluntary donors.
Family donors cannot be included amongst voluntary-non-remunerated blood donors as they have a higher rate of TTIs.

Voluntary donation is a key issue in transfusion medicine. To ensure the safety of blood transfusions, careful donor selection is important. Although new approaches to blood safety have dramatically reduced the risks for infectious contamination of blood components, the quality and the availability of blood components depend on the willingness to donate and the reliability of the information given by the donors about their own health, including risk behavior. As donors who are deferred by the blood bank will be less motivated to return for donation, it is important to reduce the number of deferrals. The aims of the present study were to investigate the reasons for deferral of registered donors coming to the blood bank for donation, in order to identify areas of importance for donor education—as these deferrals potentially could be avoided by better donor comprehension. Deferral related to testing of donors is not included in this study as these deferrals are dependent on laboratory results and cannot be indentified by questionnaire or interview. Data were collected from all blood donors in a period for 18 months who came for blood donation at a large university hospital in Norway. 1 163 of the 29 787 regular donors, who showed up for donation, were deferred (3.9%). The main reasons were intercurrent illness (n = 182) (15.6%), skin ulcers (n = 170) (14.6%), and risk behaviour (n = 127) (10.9%). In a community, intercurrent illnesses, skin ulcers, and potential risk behavior are the most frequent reasons for deferral of regular donors. Strategized effort on donor education is needed, as “failure to donate” reduces donor motivation.
Despite policies advocating centralised transfusion services based on voluntary donors, the hospital‐based replacement donor system is widespread in sub‐Saharan Africa.
To evaluate the cost of all laboratory resources needed to provide a unit of safe blood in rural Malawi using the family replacement donor system
Full economic costs of all laboratory tests used to screen potential donors and to perform cross‐matching were documented in a prospective, observational study in Ntcheu district hospital laboratory.
1729 potential donors were screened and 11 008 tests were performed to ensure that 1104 units of safe blood were available for transfusion. The annual cost of all transfusion‐related tests (in 2005 US$) was $17 976, equivalent to $16.28 per unit of transfusion‐ready blood. Transfusion‐related tests used 53% of the laboratory's total annual expenditure of $33 608.
This is the first study to provide prospective economic costs of all laboratory tests associated with the family replacement donor system in a district hospital in Africa. Results show that despite potential economies of scale, a unit of blood from the centralised system costs about three times as much as one from the hospital‐based “replacement” system. Factors affecting these relative costs are complex but are in part due to the cost of donor recruitment in centralised systems. In the replacement system the cost of donor recruitment is entirely borne by families of patients needing a blood transfusion.

Introduction: An integrated strategy for blood safety is required for the provision of safe and adequate blood. Recruiting a sufficient number of safe blood donors is an emerging challenge. The shortage of blood in India is due to an increase in the demand, with fewer voluntary blood donors. A study on the knowledge, attitude and the practice of donors may prove to be useful in the successful implementation of the blood donation programme. Our aim was to find the level of the knowledge, attitude and practice of blood donation among voluntary blood donors.
Material and Methods: A structured questionnaire was given to 530 voluntary blood donors to assess their knowledge, attitude and practice with respect to blood donations. The statistical analyses were done by using the SPSS software. The associations between the demographic factors were analysed by using the Chi square test.
Results: Among the 530 donors, 436 (93%) were males and 36 (7%) were female donors. 273 (51.2%) donors knew about the interval of the donation and 421 (79.4%) donors knew about the age limit for the donation. 305 (57%) donors felt that creating an opportunity for the donation was an important factor for motivating the blood donation and 292 (55%) donors felt that the fear of pain was the main reason for the hesitation of the donors in coming forward to donate blood.
Conclusion: A majority of the donors were willing to be regular donors. The donors showed positive effects like a sense of satisfaction after the donation. Creating an opportunity for blood donation by conducting many blood donation camps may increase the voluntary blood donations.

Introduction. In India, family/replacement donors still provide more than 45% of the collected blood. With increasing voluntary blood donation and the still-prevalent infectious diseases in donors, we need to augment transfusion-transmitted infections (TTIs) testing before use. Our study was aimed to know the seroprevalence of TTIs among the donors of Rajasthan and the need for newer technologies like nucleic acid testing (NAT). Materials and Methods. Enhanced chemiluminescence immunoassay (ECi) was used for detection of HBsAg, anti-HIV, and anti-HCV in donor serum. 50% of the blood units which were negative on ECi were randomly selected and subjected to NAT testing for HBV, HCV, and HIV. Results. The total seroprevalence of TTIs is 2.62%. Of the randomly selected donor units negative by ECi, 8 turned out to be reactive on NAT testing: 4 were voluntary and 4 were family/replacement donors. Combined NAT yield (NAT reactive/seronegative) for HIV, HCV, and HBV was 0.034% (1 in 2972 donations). All the 8 reactive samples were positive for HBV DNA. Conclusion. In countries with a high prevalence of TTIs like India there are likely to be a significant number of window period donations that can be identified by NAT which may be implemented in blood centers allover India with serological testing to provide safe blood and cost alone should not be a deterrent to the government and implementing agencies.
Donations in Greece are insufficient to cover the high transfusion needs arising from large numbers of thalassaemia and sickle cell anaemia patients and the implementation of new surgical techniques. Efforts to achieve self-sufficiency, and to render blood supplies safer and manageable must focus on recruiting and retaining more volunteer donors and on converting the large pool of replacement donors. The aim of the study was to gain insight into public perception regarding the risks of donation and transfusion and to identify the factors that would motivate more people in Greece to regularly donate blood. Questionnaires were distributed to 1600 donors at the blood bank and visitors to hospitals at 11 locations across the country. Data on demographics, donation behaviour, incentives, risk perception and attitudes towards donation and transfusion were analysed separately for volunteer and replacement donors and non-donors. The results showed that women and young people donate the least in Greece. Also, many donors do not donate because they are not reminded to. A small percentage of donors confessed to having concealed part of the truth to background questions. Overall, incentives to donate were considered important and included future availability of blood for self or family, paid leave from work and free blood tests. Recruitment and retention efforts should include better communication with current donors, and raising awareness among eligible donors. Staff should be educated in soliciting information from potential donors, and incentives should be better aligned to avoid conflict with ethical values and ensure honesty in the prescreening process.

The aim of the study was to find out the prevalence of transfusion transmitted infections (TTI) in voluntary and replacement donors. A total of 9599 donors were analysed for the prevalence of TTI over a period of 2 years.Of these 61.2% were voluntary donors and 38.8% were replacement donors. Prevalence of TTI in total donors was 0.6%. Prevalence of hepatitis B was highest (0.34%) followed by syphilis (0.11%), HIV&HCV (0.06%) and malaria (0.01%). Prevalence was more in male replacement donors. Extensive donor selection and screening procedures will help in improving the blood safety.

A blood transfusion is a life-saving procedure in many instances. An adequate supply of safe blood is ensured by exercising donor deferral criteria and screening for Transfusion Transmitted Infections (TTI). The aim of this paper is to study the profile of blood donors and reasons for donor deferral in coastal South India.
The study was conducted at a tertiary care hospital in Mangalore. All those who donated between 1 January 2008 and 31 December 2008 were included in the study. Data was collected using a pre-tested semi-structured proforma and analysed using SPSS version 11.5.
Most of the donors were under the age of 25 (42.92%).
Donors were predominantly male (95.20%). In terms of occupation, most subjects were students (28.01%) followed by businessmen (18.61%). Slightly more than three-quarters of the donors (77.20%) were replacement donors. The main reasons for deferral were consumption of medication in the past 72 hours (15.15%), hypertension (13.18%), a low haemoglobin level (12.34%) and alcohol intake in the past 72 hours (12.20%). Among the TTIs identified, most samples were positive for Hepatitis B surface Antigen – HBsAg (0.87%) or tested positive for Anti-Hepatitis C (HCV antibodies (0.36%).
From the study it was concluded that the majority of the donor population was young and educated. The reason for donation was mainly replacement rather than voluntary. This issue needs to be addressed by exercising proactive measures to increase the number of voluntary, nonremunerated, low-risk donors.

Blood is life. Transfusion of blood and blood components, as a specialized modality of patient management saves millions of lives worldwide each year and reduce morbidity. It is well known that blood transfusion is associated with a large number of complications, some are only trivial and others are potentially life threatening, demanding for meticulous pretransfusion testing and screening particularly for transfusion transmissible infections (TTI). These TTI are a threat to blood safety. The priority objective of BTS is thus to ensure safety, adequacy, accessibility and efficiency of blood supply at all levels. The objective of the present study was to assess the prevalence and trend of transfusion transmitted infections (TTI) among voluntary and replacement donors in the Department of Blood bank and transfusion Medicine of JSS College Hospital, a teaching hospital of Mysore during the period from 2004 to 2008. A retrospective review of donors record covering the period between 2004 and 2008 at the blood bank, JSS Hospital, Mysore was carried out. All samples were screened for HIV, HBsAg, HCV, syphilis and malaria. Of the 39,060, 25,303 (64.78%) were voluntary donors and the remaining 13,757 (35.22%) were replacement donors. The overall prevalence of HIV, HbsAg, HCV and syphilis were 0.44, 1.27, 0.23 and 0.28%, respectively. No blood donor tested showed positivity for malarial parasite. Majority were voluntary donors with male preponderance. In all the markers tested there was increased prevalence of TTI among the replacement donors as compared to voluntary donors. With the implementation of strict donor criteria and use of sensitive screening tests, it may be possible to reduce the incidence of TTI in the Indian scenario.

The emergence of transfusion transmitted infection (TTI) especially HIV/AIDS has created a huge obstacle in ensuring blood safety. To assess the situation in Eritrea, we carried out a retrospective study of 29,501 blood donors for the prevalence of TTI's i.e. HIV, HBV, HCV and Syphilis.
The study population included all donors who donated blood from January 2006 to November 2009. The data was collected from the National Blood Transfusion Services (NTBS) of Eritrea and includes category of donor and result for TTI markers.
A total of 29,501 units of blood were collected from 23,385(79%) voluntary blood donors and the rest 6,116(21%) units were collected from family replacement donors. The over all prevalence of TTI's were 3.8% with 3.5% in voluntary blood donors and 5.1% in family replacement donors. The sero-prevalence for TTI markers were 0.18% HIV, 2.58% HBV, 0.57% HCV and 0.49% Syphilis.
In conclusion, even if the TTI prevalence rate among Eritrean blood donors is low, ensuring blood safety has a long way to go.

Blood and apheresis donations are widely considered to be safe with a low incidence of adverse reactions and injuries; however, data reported in the medical literature on the prevalence of adverse events in donors and studies on the predictive risk factors for donor reactions are limited and contradictory.
From January 2002 to December 2006 we recorded every adverse reaction verified during 240,596 consecutive blood and apheresis donations (183,855 homologous whole blood donations, 6,669 autologous whole blood donations, 38,647 plasmapheresis, 2,641 plateletpheresis and 8,784 multicomponent donations) at the Italian Transfusion Centres of Verona and Ragusa,.
Using a special, pre-arranged form within the quality system, a total of 686 adverse reactions (related to 0.28% of all donations) were recorded. Vasovagal reactions, mostly of mild intensity, were the most commonly observed adverse reactions, with a frequency of 0.20% (487/ 240,596). The frequency of the vasovagal reactions varied according to the different types of donation, being 0.19% (346/183,855) for homologous whole blood donations, 0.24% (16/6,669) for autologous whole blood donations, 0.16% (63/38,647) for plasmapheresis, 0.68% (18/2,641) for plateletpheresis and 0.49 (43/8,784) for multicomponent donations. Citrate toxicity was reported in 0.38% (189/50,072) of apheresis donations. Severe adverse reactions were very rare, as they occurred in 0.004% of the donations (10/240,596).
In conclusion, the results of our 5-year survey document that apheresis and blood donation are safe procedures for the donor with a low incidence of adverse reactions; the adverse reactions that did occur were mostly mild and resolved rapidly.

Background and Objectives:
The blood donor system in the Kingdom of Saudi Arabia depends on a combination of voluntary and involuntary donors. The aim of this study is to explore the attitudes, beliefs and motivations of Saudis toward blood donation.
Materials and Methods:
The study was conducted at the Donor Centers at King Khalid University Hospital (KKUH) Blood Bank and King Saud University Students Health Center, Riyadh. A self-administered questionnaire was distributed to donors (n = 517) and nondonors (n = 316), between February and June 2008. All were males.
Ninety-nine percent of the respondents showed positive attitude toward blood donations and its importance for patients care, and object the importation of blood from abroad. Blood donors: Ninety-one percent agree that that blood donation is a religious obligation, 91% think no compensation should be given, 63% will accept a token gift, 34% do not object to donating six times/year and 67% did not mind coming themselves to the donor center to give blood. Nondonors: Forty-six percent were not asked to give blood and those who were asked mentioned fear (5%) and lack of time (16%) as their main deterrents. Reasons for rejection as donors include underweight and age (71%) and health reasons (19%). Seventy-five percent objected to money compensation but 69% will accept token gifts and 92% will donate if a relative/friend needs blood.
These results reflect an encouraging strong positive attitude toward blood donation. Further future planning with emphasis on educational/publicity programs and careful organization of donor recruitment campaigns could see the dream of total voluntary nonremunerated blood donations should not take long to be true.

Voluntary donors normally tolerate blood donation very well, but, occasionally, adverse reactions of variable severity may occur during or at the end of the collection. Aim of this study was to estimate and possibly avoid the cause of unwanted reactions.
Materials and methods
The study was conducted over a period of 6 months, from 24th October, 2005 to 24th April 2006. The donor population analysed consisted of 4,906 donors (3,716 male and 1,190 female). In total, 3,983 (81%) voluntaries have donated whole blood, 851 (17%) plasma from apheresis, 64 (1.3%) experienced multicomponent donation, and 8 (0.1%) were donors of plasma-platelet apheresis.
Only 63 donors (1.2% of all the volunteers) suffered some kind of adverse reaction: 59 (1.08% of the subjects) had mild reactions (agitation, sweating, pallor, cold feeling, sense of weakness, nausea), and only 4 (3 males and 1 female, 0.2%) had more severe disorders, including vomiting, loss of consciousness, and convulsive syncope.
Although the number of donors who developed disturbances during or at the end of blood donations was very low, it is nevertheless desirable to reduce risks to a minimum. A set of advices is provided for preventing problems.

This review examines the current state of transfusion services in sub‐Saharan Africa and presents the argument for and against the Western model of a centralised blood service with 100% voluntary non‐remunerated blood donors as advocated by the World Health Organization. The current practice of family replacement donors in hospital‐based blood service is the most economical option, but in the face of high child and maternal mortality rates the blood supply has proved to be insufficient. With estimates of 5–10% of HIV transmission in Africa being the result of contaminated blood transfusions, there is a need to improve testing for transfusion transmissible diseases and the selection of blood donors. Of major concern, with respect to testing, is the quality of kits being used and the continuity of supply. The need to produce components is discussed in the context of the transfusion needs in sub‐Saharan Africa. The running costs of establishing and maintaining centralised blood services need careful consideration as such projects need to be sustainable in the future. It is concluded that both options are viable while centralised programmes are being developed, and a pragmatic approach should be taken to ensure that the patients' needs are met and that resources are suitably utilised to ensure sustainability.

Appropriate selection of donors, use of sensitive screening tests, and the application of a mandatory quality assurance system are essential to maintain the safety of the blood supply. Laws, decrees, norms, and/or regulations covering most of these aspects of blood transfusion exist in 16 of the 17 countries in Latin America that are the subject of this review. In 17 countries, there is an information system that, although still incomplete (there are no official reports on adverse events and incidents), allows us to establish progress made on the status of the blood supply since 1993. Most advances originated in increased screening coverage for infectious diseases and better quality assurance. However, in 2001 to 2002, tainted blood may have caused infections in 12 of the 17 countries; no country reached the number of donors considered adequate, i.e., 5% of the population, to avoid blood shortages, or decreased significantly the number of blood banks, although larger blood banks are more efficient and take advantage of economies of scale. In those years, paid donors still existed in four countries and replacement donors made up >75% of the blood donors in another eight countries. In addition, countries did not report the number of voluntary donors who were repeat donors, i.e., the healthiest category. In spite of progress made, more improvements are needed.
In Switzerland, blood donations are collected exclusively from healthy non-remunerated voluntary blood donors mainly by 13 regional Blood Transfusion Services throughout the country. Thereby, self-sufficient blood supply for a population of about 7.5 million is achieved, and approximately 300,000 units of red cells, 75,000 therapeutic units of fresh plasma, and 20,000 therapeutic units of platelets are transfused annually. Reporting to Swissmedic (the Swiss agency for therapeutic products) of all suspected adverse transfusion events on a standardised form is mandatory. Data are then analysed to estimate the risks of the most serious transfusion events. Together with transfusion of an incorrect blood component and bacterial contamination of platelet concentrates, TRALI is a significant risk of transfusion in Switzerland and occurs in approximately every 8,000–20,000 FFP transfusions according to current haemovigilance data. Among 25 reported cases between 2002 and November 2007, 4 are proven immune TRALI, 2 are highly likely immune TRALI, 10 are possibly immune TRALI, 8 are non-immune TRALI, and 1 is a suspected case which could not be confirmed as TRALI. Based on the hypothesis of an immunological trigger of TRALI, an exclusion of the transfusion of plasma from female donors can be considered as a precautionary measure which might have prevented 4 cases of proven immune TRALI, 2 cases of highly likely immune TRALI, and an unknown number of the 10 cases of possibly immune TRALI. Based on these data and encouraging preliminary reports of the effects of comparable measures in other countries, the decision was made that starting with January 1st 2007 the production of quarantined FFP is restricted to donations from men or from women confirming that they have never been pregnant (to their knowledge) or with negative tests for antibodies against HLA class I and II. The analysis of further vigilance data is needed to elucidate the efficacy of this preventive measure.

In the Soviet period, the blood donation system operated in Lithuania exclusively on a remunerative basis. After joining the EU, Lithuania committed itself to meeting the EU requirements to provide all consumers within its boundaries with safe blood products made from voluntary unpaid blood donations. However, the introduction of a non-remunerated donation system may considerably affect donors' motivation and retention. Thus the aim of the current research was to determine blood donation motives among the present donors and investigate their attitude towards non-remunerated donation.
A questionnaire survey of 400 blood donors. Survey data processed using SPSS statistical analysis package. Statistical data reliability checked using Fisher's exact test (p < 0.05).
Paid donors comprised 89.9%, while non-paid ones made 10.1% of the respondents. Research findings show that 93 per cent of the paid donors give blood on a regular basis; while among the non-remunerated donors the same figure amounted merely to 20.6 per cent. The idea of the remuneration necessity is supported by 78.3 per cent of the paid donors, while 64.7 per cent of the non-remunerated respondents believe that remuneration is not necessary. The absolute majority of the paid donors (92%) think they should be offered a monetary compensation for blood donation, while more than half of the non-remunerated donors (55.9) claim they would be content with a mere appreciation of the act. Provided no remuneration were offered, 28.44 per cent of the respondents would carry on doing it, 29.6 per cent would do it only in emergency, 29.6 per cent would donate blood merely for their family or friends, and 12.3 per cent would quit it completely.
Most respondents admitted having donated blood for the following reasons: willingness to help the ill or monetary compensation. Majority would consent to free blood donation only in case of emergency or as a family replacement, which leads to a conclusion that provided monetary remuneration is completely terminated part of the currently active paid donors would withdraw from this activity, which might seriously affect the national supply of blood and its products.
Knowledge about the frequency of red blood cell-antigen phenotypes in a population can be helpful in the creation of a donor data bank for the preparation of indigenous cell panels and for providing antigen-negative compatible blood to patients with multiple alloantibodies.
ABO and RhD blood grouping was performed on 9,280 continuous voluntary and replacement donors. For other rare blood groups, 508 ACD blood samples were obtained from the donors at the Blood Bank of the Department of Transfusion Medicine, All India Institute of Medical Sciences (AIIMS), New Delhi, India. Blood group antigens were determined by tube method using anti-sera (Bio-Rad, USA), and the phenotype frequencies were expressed as percentages.
Group B (37.39%) was the most common, followed by group O (31.85%). R1R1 and rr were the most common phenotypes amongst Rh positive and Rh negative groups, respectively. A rare phenotype R2Rz was found in one donor. For Kidd and Duffy blood group systems, Jk (a+b+) and Fy (a+b+) were the most common phenotypes (46.06% and 48.03%, respectively). The most common phenotypes for MNSs, Lu, and Kell blood groups were M+N+, S-s+, Lu (a-b+), and K-k+, respectively. A very rare case of Fy (a-b-) and Jk (a-b-) was found in a single donor.
This study is the first small step to create a rare donor data bank and to prepare indigenous cell panels to provide compatible blood to all multi-transfused alloimmunized patients.

The National Blood Policy in India relies heavily on voluntary blood donors, as they are usually assumed to be associated with low levels of transfusion‐transmitted infections (TTIs). In India, it is mandatory to test every unit of blood collected for hepatitis B, hepatitis C, HIV/AIDS, syphilis and malaria. Donors come to the blood bank with altruistic intentions. If donors test positive to any of the five infections, their blood is discarded. Although the blood policy advocates disclosure of TTI status, donors are not, in practice, informed about their results. The onus is on the donor to contact the blood bank. Out of approximately 16 000 donations in the past 2 years, 438 tested positive for TTI, including 107 for HIV. Only 20% of the donors contacted the blood bank; none of them were HIV positive. Disclosure by blood banks of TTI status by telephone or mail has resulted in serious consequences for some donors. Health providers face an ethical dilemma, in the absence of proper mechanisms in place for disclosure of test results, regarding notification to donors who may test positive but remain ignorant of their TTI status. Given the high cost of neglecting to notify infected donors, the authors strongly recommend the use of rapid tests before collecting blood, instead of the current practice, which takes 3 h to obtain results, and disclosure of results directly to the donor by a counsellor, to avoid dropouts and to ensure confidentiality.
Blood transfusion services are a vital part of the national health delivery system. The responsibility for ensuring a continuous supply of blood rests with health administrators, who need to galvanize entire communities towards regular and non-remunerated blood donation.
The present study aimed to examine the prevailing global regulations and practices related to blood transfusion and press the case for a dedicated blood law in India.
Materials and Methods:
We attempted a comprehensive, annotated assembly of published studies on blood transfusion services in India.
Data Abstraction and Synthesis:
Laws related to blood transfusion services exist in India as a part of the Drugs and Cosmetics Law. In the developed world, most blood donors are unpaid volunteers who give blood for a community supply. In order to augment safe blood transfusion services in India, we have to develop operational legal guidelines on recruitment and retention of voluntary blood donors to direct related organizations for this imperative activity.
Several factors, such as political will and a professional and ethical approach can help in formulating a common vision, building trust, by providing optimum information towards a social movement for the rational blood transfusion services. We have to come together for a dedicated blood law in order to improve the quality of blood transfusion services in India.

Blood donors are of voluntary and replacement type. All donors, especially voluntary, are considered as slow risk for seropositive status for Hepatitis B and C, HIV and syphilis. The present study endeavors to screen blood donors-a slow risk group and evaluate the resultant data.
We screened 23,068 donors serologically over 2 years for the above blood transmissible diseases. Serum alanine aminotranferase (ALT) and bilirubin were evaluated as surrogate markers in hepatitis B and C positive donors.
Seroprevalence rates were found to be HIV (1.96 %), syphilis (2.15 %), hepatitis B (1.98 %) and hepatitis C (0.9 %). Majority donors were voluntary (70.37 %) and male (96.2 %). However seroprevalence rates showed no significant difference: voluntary (7.02 %), replacement (6.67 %) male (6.85 %) and female (6.95 %). HCV and HIV showed highest (29.6 %) while HBV and HCV (2.5 %) showed lowest concomitance. Serum ALT and bilirubin were not effective surrogate markers. No demographic or behavioral variable was found as a significant risk factor.
Thus, all donors need adequate privacy, information, counseling and motivation in order to reduce the seropositive rates in donors. Advent of sensitive tests renders surrogate markers redundant.

In 2006 in Italy 2,404,267 donations of blood components were made by 1,539,454 donors; approximately 55% of the donations were collected directly by Transfusion Structures (TS), while about 45% were collected in Donation Centres managed by Associations and Federations of Donors. The aim of the READ (Rilevamento Eventi Avversi alla Donazione) project is to create a network of TS to test a standardised system for monitoring adverse events (AE) related to blood donations.

Shared, standardised data collection forms, compatible with the forms produced by the ISBT-EHN, were prepared. Two types of form were used: (i) a form to collect data on single events (READ 1), to be used at the individual collection sites; (ii) a form for processing the data collected by each TS (READ 2).
Between February and August 2008 six TS collected data related to the donation of 89,332 units of blood. Overall, 523 AE were recorded. The AE occurred in 0.59% of the donations. The mean duration of the symptoms was 17 minutes. Fifteen percent of the symptoms were related to the venipuncture (mainly haematomas) and 77% to vasovagal AE. The AE were defined severe (grade C) in 47 cases. The donations in which AE were recorded were completed in 81% of the cases; 59% of the AE did not require treatment. Three donors were monitored briefly (for less than 4 hours) in hospital.
The use of standardised forms enabled the collection of data that could be analysed. Some problems related to the performance of the haemovigilance programme did, however, emerge: (i) organisational problems, (ii) limited sensitivity, (iii) inadequate training, and (iv) poorly defined responsibilities. These problems must be resolved at various levels: local, regional and national.
blood donation; adverse events to donation; Italian multicentre study
Our blood bank is a regional blood transfusion centre, which accepts blood only from voluntary donors.
The aim is to study iron status of regular voluntary donors who donated their blood at least twice in a year.
Materials and Methods:
Prior to blood donation, blood samples of 220 male and 30 female voluntary donors were collected. Control included 100 each male and female healthy individuals in the 18- to 60-year age group, who never donated blood and did not have any chronic infection. In the study and control groups, about 10% subjects consumed non-vegetarian diet. After investigation, 85 males and 56 females having haemoglobin (Hb) levels above 12.5 g/dl were selected as controls. Donors were divided into ≤10, 11-20, 21-50 and >50 blood donation categories. Majority of the donors in >50 donation category donated blood four times in a year, whereas the remaining donors donated two to three times per year. Haematological parameters were measured on fully automatic haematology analyzer, serum iron and total iron-binding capacity (TIBC) by biochemical methods, ferritin using ELISA kits and transferrin using immunoturbidometry kits. Iron/TIBC ratio × 100 gave percentage of transferrin saturation value.
Statistical evaluation was done by mean, standard deviation, pair t-test, χ2 and anova (F-test).
Preliminary analysis revealed that there was no significant difference in the iron profile of vegetarian and non-vegetarian subjects or controls and the donors donating <20 times. Significant increase or decrease was observed in mean values of various haematological and iron parameters in donors who donated blood for >20 times (P < 0.001), compared to controls. Anaemia, iron deficiency and depletion of iron stores were more prevalent in female donors (P < 0.05) compared to males and especially in those male donors who donated their blood for more than 20 times.
Regular voluntary blood donors should receive iron supplementation to prevent iron deficiency and depletion in iron stores.
