Order Prothrombin Test: Prothrombin Time PT with INRThe prothrombin test evaluates how efficiently blood forms a clot by measuring specific components of the coagulation cascade. It reports the prothrombin time (PT), the international normalized ratio (INR), and often the activated partial thromboplastin time (aPTT). Together, these values give a structured view of both the extrinsic and intrinsic clotting pathways, which is why the test is used in a wide range of clinical settings.
About Prothrombin Test: Prothrombin Time PT with INR in Ontario
Clotting is a tightly regulated sequence of events, and the prothrombin test captures key steps within it.
The prothrombin time measures how long it takes plasma to clot after tissue factor and calcium are added. This assesses the extrinsic and common pathways, including factors II, V, VII, and X, as well as fibrinogen. A prolonged PT can point to factor deficiencies, liver dysfunction, vitamin K deficiency, or the effect of anticoagulant medications.
The INR is a standardized ratio derived from the PT. Because PT results vary between laboratories depending on the reagents used, the INR applies a correction that makes values comparable across different settings. It is most familiar as the value used to monitor warfarin therapy, where a target range is typically set by the prescribing clinician.
The activated partial thromboplastin time, when included, evaluates the intrinsic and common pathways. It is sensitive to factors VIII, IX, XI, and XII, among others, and is commonly used to investigate unexplained bleeding or to monitor unfractionated heparin. Reading PT, INR, and aPTT together helps distinguish which part of the clotting system may be affected.
