APTT

325.00

The aPTT is one of several blood coagulation tests. It measures how long it takes your blood to form a clot.

Normally, when one of your blood vessels is damaged, proteins in your blood called clotting factors come together in a certain order to form blood clots and quickly stop bleeding. The aPTT test can be used to look at how well those clotting factors are working. It’s often used with other tests that monitor clotting factors.

Blood clots form in a specific series of steps called a pathway. This test mainly looks at how both the intrinsic clotting pathway and the common final pathway are working. You may need this test if your healthcare provider believes that you have a problem with 1 or more clotting factors. If you have a bleeding disorder such as von Willebrand disease or another disease that prevents your blood from clotting, this test can help find out where the problem is.

This test is also used to monitor people who are getting heparin therapy. Heparin is a blood thinner used to prevent dangerous blood clots.
