Introduction: The incidence of ABO and Rh blood groups varies markedly in different parts of India. Knowledge about blood group distribution is useful in blood bank inventory management thereby reducing morbidity and mortality. It is also useful for parental testing, legal medicine and population genetic studies

Material and Methods: The study was conducted in GIMSR Blood bank and local licensed blood bank in north coastal Andhra Pradesh Visakhapatnam over a period of 3 years from 1 April 2015 to 31 march 2018.ABO blood grouping and Rh typing were done by Gel card and tube agglutination methods.

Results: During this period 70173 blood groups were performed. The study revealed the commonest blood group was O (39.12%) followed by B(30.57%),  A(24.78%) and AB (5.53%)

Conclusion: The most common blood group in our donors was O positive and the least common was AB negative.
