PT1（Cat No.:I010882）, or Prothrombin Time 1, is a blood test used to assess the time it takes for blood to clot. It evaluates the extrinsic pathway of coagulation and monitors factors I (fibrinogen), II (prothrombin), V, VII, and X. PT1 is commonly used to screen for bleeding disorders, liver function issues, and to monitor patients on warfarin therapy. Abnormal PT1 values may indicate clotting deficiencies, liver disease, or vitamin K deficiency. It plays a crucial role in diagnosing coagulopathies and guiding anticoagulant dosing in clinical practice.
