Trends of A B O, Rh Positive and Rh-Negative Blood Groups in Voluntary Non-Remunerated Blood Donors in Tertiary Care Hospital Blood Centre, Maharashtra, India.

Abstract

The term “blood group” refers to the entire blood group system comprising
red blood cell (RBC) antigens whose specificity is controlled by a series of genes that can be
allelic or linked very closely on the same chromosome. “Blood type” refers to a specific
reaction pattern to testing antisera within a given system.1 The ABO blood group antigens
remain important in transfusion medicine as they are the most immunogenic of all the blood
group antigens. The most common cause of death from a blood transfusion is a clerical error
in which an incompatible type of ABO blood is transfused. The ABO blood group antigens
also appear to have been important because the frequencies of different ABO blood types
vary among various populations. Aim: This study aims to know the Trend of A, B, O, Rh-
positive, and Rh-negative blood Groups in Voluntary non-remunerated blood Donors in the
Tertiary Care Hospital Blood Centre, India.
