Factor V Inhibitor Screen, Plasma
Use
This test is used for detecting the presence of a specific factor inhibitor directed against coagulation factor V. An inhibitor directed against a coagulation factor may arise due to multiple exposures from transfusions in a patient deficient in that factor, in response to certain disease states, or be drug-induced. Nonspecific inhibitors may also be present in patients that will prolong screening tests such as prothrombin time and activated partial thromboplastin time.
Special Instructions
Not provided.
Limitations
This test may occasionally produce false-positive results in the presence of a potent lupus-like anticoagulant which can interfere with the detection of a specific factor inhibitor.
