Frequency and Distribution of ABO and Rhesus Blood Group of Blood Donors

Abstract

Introduction: ABO blood group was discovered by Landsteiner in 1900. ABO and Rhesus blood group antigens are important in transfusion medicine and its incidence differ in races, ethnic groups and socioeconomic groups. Material and Methods: This retrospective study was conducted in blood bank of district hospital associated with government medical college, Khandwa during 6-months period between 1 January 2019 to 30 June 2019. 3300 individuals were considered fit for donating blood. Age range between 18 and 60 years. The donors who's haemoglobin more than 12.5 gm% were selected and screened by medical officer. ABO and Rhesus blood groups were determined by slide test and tube method. Results: The common age group for blood donation was 21-30 years. Out of 3300 donors, 98% were males and 2% were female. The commonest blood group was B (33.91%) followed by O (29.12%), A (26.78%), AB (10.29%). ABO blood group pattern in decreasing order was B > O > A > AB. Rh-positive donors were 95.3% and Rh negative were 4.7 %. Conclusion:This Blood group study will be helpful in health care planning, running of organized, efficient and safe blood transfusion services.

Frequency of ABO and Rhesus blood groups in Saudi healthy blood donors versus non-Saudi in a retrospective study in Makkah City

“…This is in accordance with previous studies with few discrepancies [14, 18-19, 22, 34-40]. In India, certain regions had a higher frequency of O and others of B or A [18,22,41]. In Thailand, the frequency was O>B>A>AB and not O>A>B>AB [38,39].…”

The frequency of ABO and Rhesus(D) blood group antigens among blood transfused patients in Northern Ethiopia, 2023: Retrospective study

“…However, blood plasma contains reverse antibodies that are directed against specific antigens. A and B antigens are highly antigenic, with naturally occurring antibodies in human plasma that are antigen-free and can cause hemolysis in vivo [ 8 ].…”
