11.
A 21-year old male soccer player is admitted for surgery to repair a hernia. Routine Coagulation Lab assays reveal a prolonged APTT, normal PT, normal TCT, and the CBC reported normal platelet levels.

Factor VIII autoantibody (i.e., “inhibitor”)

FV deficiency

Which other assay did you order to help you interpret these results and what is your diagnosis (TCT, thrombin clot time; APTT, activated partial thromboplastin time; BT, bleeding time; PT, prothrombin time)?:
