Frequency of ABO and Rh Blood Group Distribution at Debre Tabor Blood Bank, Amhara Region, North-Central Ethiopia. A Six-Year Retrospective Survey

Abstract

Introduction

Blood is arranged into four groups based on their surface antigen (A, B, AB, and O). In addition to this classification based on the Rhesus factor, each blood group clustered into RH positive and RH negative. This study was done to identify the distribution of blood group and rhesus factors on the local blood bank.

Objective

To identify the frequency of ABO blood group and RH factors distribution on voluntary blood donator at Debre Tabor blood bank from May 2014 to May 2020.

Methods

A retrospective cross-sectional survey was conducted to identify the frequency of ABO and Rh factor distribution on voluntary blood donors at Debre Tabor town blood bank. The data was collected at Debre Tabor blood bank. A six-year data and a total of 19,901 bags collected blood samples were used for summarization of the data. The data was analysed by using SPSS version 21.

Results

Blood group ”O” was the dominated one with 39.6% followed by blood group “A”, “B” and “AB” with 29.48%, 24.06%, and 6.7%, respectively. When we see the RH classifications, RH positive accounts the highest percentage 92.77% and the remaining 7.23% was Rh negatives.

Conclusion

In this survey, the majority of blood groups were found “O” followed by “A”, “B”, and “AB”. Among the collected blood unities, 92.77% was RH positive. The leading blood donators were male.
