PT (PROTHROMBIN TIME)

The PT Test or Prothrombin Time Test is a blood test that measures how long it takes for blood to clot. It is mainly a test given to detect bleeding problems, monitor people taking anticoagulant medication, or for pre‐surgical workups.

Why Do I Need It?:

If you’re heading into surgery, your doctor or plastic surgeon will want to make sure your blood will clot and there aren’t any problems. It’s also used to find a cause for abnormal bleeding/bruising, to monitor how well your liver is working, and see if your blood‐thinning medicine is working.

Normal Range

No anticoagulant medications1.0 – 1.4
On anticoagulant medications2.0 – 3.0




High Results Indicate:

Elevated results are usually 2.5 – 3.5 depending on your medications. Elevated levels can indicate that your blood is taking too long to clot.


Low Results Indicate:


Low levels can indicate that your blood is clotting too quickly.
