Demographic Distribution and Prevalence of ABO and Rhesus Blood Groups in Blood Donors: Study from a Tertiary Care Centre in Southern Region of Andhra Pradesh
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 7
Abstract
Introduction: ABO and Rhesus (Rh) blood grouping and typing are the two main pillars of foundation for appropriate functioning and safe blood banking. The blood groups carry genetic information. Among twenty discovered blood group systems ABO and Rh remain as the most important ones clinically. Materials and Methods: A retrospective study was carried with 43839 blood donors’ records. The blood group was determined by forward grouping (cell grouping) and reverse (serum grouping) grouping methods. Gene / allelic frequencies of the variables were calculated. Results: Total number of blood units collected was 43839; from January 2012 to December 2017. The study showed there were 93.37% of male donors and 6.62% of female donors. The percentage of ABO blood groups in descending order in present study is noticed as O>B>A>AB. There were 95.96% of Rh positive and only 4.03% of Rh negative blood units. Allele distribution was calculated for IA (p); IB (q) and IO (r) as 0.0525; 0.2723 and 0.6752 respectively. Conclusion: The most common blood group - ‘O’ Positive (44.53%) and the least common was ‘AB’ Negative (0.51%). The data helps in appropriate maintenance of inventory in the blood bank and also helps health care professionals to formulate proper steps to ensure accurate blood transfusion protocol, safe blood transfusion during any sort of health challenges and calamities.
