AbstractBombay phenotype is an uncommon blood type. It is found in approximately 1 in 10,000 people in the Indian subcontinent and approximately 1 in 1,000,000 in Europe. The lack of the H antigen (foundation stone of the ABO blood system) on red blood cells (RBCs) and in secretions is the hallmark of this phenotype. Individuals lacking this antigen do not produce A or B antigens and appear as type O on routine blood grouping. Herein, we report an incidental discovery of a family with three members having Bombay phenotype on routine antenatal examination. Key Words: ABO blood group system, Bombay phenotype, Cross matching.
