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.
