The ABO blood group system was the first to be discovered; still, there is an enigma in ABO subgroups. The A and A phenotypes account for about 99% of all A or AB blood group individuals, and the rest are the weaker subgroups. They usually are suspected in cases of blood group discrepancies. Meticulous serological testing with technical expertise will help to differentiate these subgroups. We describe a case of a healthy blood donor with blood group discrepancy due to a weak subgroup of 'A' in the AB blood group.
ABO血型系统是最先被发现的；然而，ABO亚型仍存在一个谜团。A和A1表型约占所有A或AB血型个体的99%，其余为较弱的亚型。在血型不符的病例中通常会怀疑到它们。具备专业技术的细致血清学检测将有助于区分这些亚型。我们描述了一例健康献血者的病例，其血型不符是由于AB血型中“A”的一个弱亚型所致。
