Coagulation factor inhibitors arise in patients who are congenitally deficient in a specific factor in response to factor replacement therapy, or can occur spontaneously without known cause or in response to a variety of medical conditions including the postpartum state, immunologic disorders, certain antibiotic therapies, some malignancies, and old age.
Inhibitors of factor VIII coagulant activity are the most commonly occurring of the specific factor inhibitors.
Only orderable as part of a profile. For more information see 7INHE / Factor VII Inhibitor Evaluation, Plasma.
An interpretive report will be provided.
Occasionally, a potent lupus-like anticoagulant may cause false-positive testing for a specific factor inhibitor (eg, factor VIII or IX).
