The prothrombin time (PT) with INR and partial thromboplastin time (PTT) is a group of blood clotting tests. It is ordered to check how well your blood clots and to monitor conditions or medicines that affect clotting.
What it measures
- Prothrombin Time (PT) — Time in seconds for blood to clot via the extrinsic pathway.
- INR — Standardized ratio of PT to normal, used to monitor warfarin and liver function.
- Partial Thromboplastin Time (PTT) — Time in seconds for clotting via the intrinsic pathway.
- Fibrinogen — Sometimes measured; a protein essential for clot formation.
Who it is for
A doctor may order this test if you have unexplained bleeding or bruising, a known clotting disorder, or are taking blood-thinning medicine like warfarin or heparin.
Preparation
No fasting is needed. Tell your doctor about all medicines, especially blood thinners, and follow any specific instructions about timing.
Results and what they mean
