Background. Racial differences in blood group antigen distribution are common and may result in striking and interesting findings. These differences in blood group antigen distribution are important due to their influence on the clinical practice of transfusion medicine. Study Design and Methods. This is a prospective study, involving 1000 healthy regular repeat voluntary blood donors associated with the department. The clinically significant minor blood group antigens of these donors were studied. Results. Out of 1000 healthy regular repeat voluntary blood donors, 93% were D positive and 2.8% were K positive. Amongst the Rh antigens, e was the most common (99%), followed by D (93%), C (85.1%), c (62.3%), and E (21.5%). Within the MNS blood group system, antigen frequency was M (88%), N (57.5%), S (57.8%), and s (87.5%). Within the Duffy blood group system, antigen frequency was Fya (87.3%) and Fyb (58.3%). Conclusions. This data base will help us to prevent alloimmunisation in young females, pregnant women, and patients who are expected to require repeated transfusions in life by providing them with antigen matched blood. Antigen negative blood can also be made available without delay to already alloimmunized multitransfused patients.

The coronavirus pandemic has impacted and pushed the healthcare settings to extremes across the globe. It was extremely challenging to sustain blood donation, and strategies could be formulated on knowing fears hindering blood donation.Methods A cross-sectional survey using Google Forms â through WhatsApp and email after obtaining the ethical clearance. The survey questionnaire was validated for content using the Delphi technique, and pilot tested for finalization. ResultsThe survey was attempted by 1066 participants, and 749 participants who had not donated since pandemic were included in the study. A little more than half, 415 (55%) reported either one or more than one fear during the pandemic which hindered blood donation. They reported lack of confidence in the safety measures at the hospitals and fear of transmitting infection to family, in 415 (55%) of the participants each, respectively. The fear of COVID-19 hospital infection risk and hospital entry was statistically significant across the age groups that are eligible for blood donation. ConclusionsThe clear and dedicated confidence building measures to sustain blood donation using all communication modalities clearly emerge as the most important strategies to augment blood donation in the COVID-19 pandemic. The measures should include information about implementation of safety measures to mitigate COVID-19 transmission at the blood centres and that the act of blood donation does not increase risk of COVID-19 and therefore the risk of transmission of infection to family.

World Health Organization (WHO) recommends screening of syphilis in low prevalence populations of blood donors by treponemal tests like enzyme-linked immunosorbent assay (ELISA), whereas in India screening is done by rapid plasma reagin (RPR). The present pilot study evaluated the performance of ELISA compared to RPR, keeping Treponema pallidum hemagglutination assay as a reference test. ELISA was equally sensitive (100%), more specific (56.3% vs. 0%), more accurate (83.7% vs. 62.7%), had better positive predictive value (79.4% vs. 62.8%) and negative predictive value (100% vs. 0%), and less biological false positivity (37.2% vs. 20.6%) when compared to RPR. The WHO recommendations of screening for syphilis in low prevalence population of blood donors using ELISA may be adopted for usage in transfusion services that have the facility of ELISA.

Introduction:The blood mobile is one of the modern methods of mobile blood collection facility funded through the third phase of National AIDS Control Programme by the National Blood Transfusion Council of India.Material and Methods:A retrospective analysis of data in relation to the blood mobile was carried out with respect to the number of blood donation camps, number of blood units collected, adverse donor reactions, and the expenditure that occurred during the blood collection in the blood mobile from 1st January 2012 to 30th June 2014.Results:There were 64, 84 and 62 blood donation camps conducted in the blood mobile with collection of 3301, 5166 and 2842 blood units during 2012, 2013 and the first half of 2014. The percentage of voluntary blood collection in blood mobile was 8.5% in 2012, increased to 12.4% in 2013 and stands at 14.39% in the first half of 2014. The difference in the means of the adverse donor reactions in the blood mobile and the outdoor camps was not statistically significant.Discussion and Conclusion:The blood mobile is definitely an asset as far as augmentation of voluntary blood donation is concerned, ensures stable collection of blood for better provision of blood and blood components. However the facility requires a comprehensive annual maintenance with incorporation of onsite quick response team both from the manufacturer of the vehicle, and the blood collection equipments. Adequate provision of funding for operational expenditure would in turn facilitate optimum utilization of this facility.
