Factor II Inhibitor Screen, Plasma
Use
The test is useful for detecting the presence of a specific factor inhibitor directed against coagulation factor II. An inhibitor against a coagulation factor may develop due to multiple transfusions or as a response to certain diseases or medications. This test helps in detecting such inhibitors, which can affect normal blood coagulation and prolong screening tests.
Special Instructions
Only orderable as part of a profile. For more information, see 2INHE / Factor II Inhibitor Evaluation, Plasma; ALBLD / Bleeding Diathesis Profile, Limited, Plasma; APROL / Prolonged Clot Time Profile, Plasma. Refer to the Coagulation Guidelines for Specimen Handling and Processing for detailed collection instructions.
Limitations
Occasionally, a potent lupus-like anticoagulant may cause false-positive testing for a specific factor inhibitor, such as factor VIII or IX. The presence of non-specific inhibitors may also prolong screening tests like prothrombin time and activated partial thromboplastin time.
