The aPTT is one of several blood coagulation tests. It measures how long it takes your blood to form a clot. When one of your blood vessels is damaged, proteins called clotting factors come together to form clots and quickly stop the bleeding. The aPTT test helps assess how well those clotting factors work, often in conjunction with other tests that monitor clotting factors.
