Abstract

A survey was conducted to investigate into the frequency of different blood groups in Punjab. A total of 1415 persons were included in this survey. The slide method was used for determination of ABO and AB blood groups as well as Rh factor. The frequency of blood group A was 21.20%; B, 36.16%; AB, 9.05% and O, 34.14%. Distribution of blood groups among various castes revealed the incidence of blood group A, 13.57% to 30%; B, 28.125% to 50%; O, 16.67% to 40%; and AB, zero to 25%. Only 2.76% cases were found to be Rh negative. Rh negative frequency was much higher in Baluchs, Awans and Gujjars than Rajputs, Jats and Arains.
