What is the distribution of ABO blood types?

The ABO blood group was determined by agglutination using the antibodies anti-A, Anti-B, and Anti-D for the Rh factor, respectively. Results. The overall distribution of ABO and Rh (D) groups in the population studied was as follows: O: 61.82%; A: 27.44%; B: 8.93%; and AB: 1.81%.

What is the distribution of blood group ABO system according to who?

The study revealed that blood group O was the commonest (37.12%) closely followed by B at 32.26%, followed by A at 22.88% and AB was the least prevalent group at 7.74%. Out of the total donor population, 94.61% were Rh (D) positive and rest 5.39%, were Rh (D) negative [Table 4].
