Answer

Answer

If, after an adequate infusion of VII, VIII, IX, XI, and V, bleeding continues, a factor-inhibitor assay is indicated. Although nearly all procoagulants have an inhibitor, the inhibitor to factor VIII is the most common.

Under normal circumstances, no factor inhibitors are present.
