The two lab tests that would be ordered to assess the inhibitor in a hemophiliac are Factor VIII:C level and Bethesda titer. Factor VIII:C level will determine the amount of clotting factor VIII in the patient's blood, while Bethesda titer will measure the strength of the inhibitor in the patient's blood.
