Four units of group A platelets were transfused to a group AB patient as group AB platelets were not available. The patient's pre transfusion platelet count was 10,000/uL and the post transfusion could was 16,000/uL. From this information, the laboratorian would most likely conclude that the patient:
A. Needs group AB platelets to be more effective
B. clinical data does not suggest a need for platelet transfusion
C. Has developed antibodies to the transfused platelets
D. Should have received irradiated platelets
