The antioxidant defense in A, B, and O groups were similar as evident from our results of Hb, antioxidant enzymes and sulfhydryls. However, the response of blood group O diverged from that of A and B, substantiated by the results of MDA, AOPP, and superoxides. Thus blood group O endured oxidative insult more efficiently than A and B. This study forms the basis for future studies on erythrocyte membrane and exploring blood group O as a potential candidate for prolonging storage.
