Useful for diagnosing a congenital deficiency of coagulation factor II, for evaluating acquired deficiencies associated with liver disease or vitamin K deficiency, oral anticoagulant therapy, and antibody-induced deficiencies (eg, in association with lupus-like anticoagulant). Also useful for determining warfarin treatment stabilization in patients with nonspecific inhibitors (ie, lupus anticoagulant), determining degree of anticoagulation with warfarin to correlate with level of protein S, and the investigation of prolonged prothrombin time or activated partial thromboplastin time.
Useful for patients with clinically suspected thrombophilia and either activated protein C (APC)-resistance proven or suspected by a low or borderline APC-resistance ratio, or a family history of factor V Leiden.
