Special Info

Indicate clearly if patient is on heparin, coumadin, direct thrombin inhibitor or thrombolytic therapy. If tests are abnormal, the following tests may be added and billed: Fibrinogen Ag (CPT 85385), D-Dimer (CPT 85379), Reptilase (CPT 85635).

Clinical Info

Note: It is recommended that the abnormal PT be confirmed before ordering this panel. This panel is intended to assist in the diagnosis of coagulation disorders in patients with a prolonged PT, but normal PTT, whether or not there is a bleeding diathesis. Disorders that may be investigated include the extrinsic and common pathway factor deficiencies (factor II, V, VII, X and fibrinogen), coagulation factor inhibitors, non-specific inhibitors, vitamin K deficiency, hepatic coagulopathy, disseminated intravascular coagulation (DIC), hypofibrinogenemia, dysfibrinogenemia, or anticoagulant drug effects.
