Abstract
-
Two cases of ABO discrepancy were observed in thirty-year old woman with gall bladder abscess and fifty-five-year old woman with hepatocellular carcinoma. Their red cells were typed as group O and their serum had only anti-A antibody. Absence of A and B antigens on their RBCs were confirmed by adsorption elution test and saliva test. The B transferase activities were not demonstrated in their serum. Their ABO genotypes were O/O by sequence specific polymerase chain reaction. Their serum protein electrophoresis showed hypogammaglobulinemia pattern, and immunoglobulin levels (IgG, IgA, IgM) were decreased (39 mg/dL, 46 mg/dL, <5 mg/dL and 63 mg/dL, 65 mg/dL, 12 mg/dL, respectively).
