   What is a PTT test?

   • A PTT test looks at one set of these factors to see how well they’re working. It’s often done along with another test, called the prothrombin time (PT) test, which looks at another set of clotting factors. Together, they give your doctor a more complete picture of what happens in your body when a clot forms.

Higher than that means your blood is taking longer than normal to clot and may be a sign of many conditions, including: If you have a lower number, your blood clots faster than normal.

   How long does a PTT test take?

   • Usually, you get the results within a few hours or a day, but it depends on your lab. A typical value for a PTT is 60 to 70 seconds. There’s also an activated PTT (aPTT) test that measures the same thing, but they add a substance to your blood to make it clot faster. A typical aPTT value is 30 to 40 seconds.
