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
Results are reported as seconds for PT and PTT, and as a number for INR. Your clinician interprets these values based on your health and medicines. This is general information, not medical advice.

Frequently asked questions
What does a high INR mean?
A high INR means your blood clots more slowly than normal, which can increase bleeding risk. Your doctor will determine the cause and next steps.
Do I need to stop my blood thinner before the test?
No, unless your doctor tells you to. The test is often used to check if your dose is right.
How long does it take to get results?
Typically 1 to 3 business days, but it may be faster in urgent situations.
Can I eat or drink before the test?
Yes, no fasting is required. You can eat and drink normally.
