Diagnostic Analysis
The patient was experiencing a blood transfusion incompatibility reaction. His direct Coombs
test and haptoglobin studies indicated some hemolysis because of the reaction. His platelet count
dropped because of antiplatelet antibodies, probably the same ABO antibodies that caused the
RBC reaction.
He was given iron orally over the next 3 weeks, and his Hgb level improved. A rectal
examination indicated that his stool was positive for occult blood. Colonoscopy indicated a right-
side colon cancer, which was removed 4 weeks after his initial presentation. He tolerated the
surgery well.
