Your doctor may recommend a factor VIII assay test to determine whether your body produces a healthy level of this particular coagulation factor. Your body needs factor VIII in order to form blood clots. Each time you bleed, it triggers a series o...
A platelet aggregation test checks how well your platelets clump together. Platelets are types of blood cells. They help form blood clots by sticking together. A clot stops the bleeding when you have a wound. A platelet aggregation test requires a...
A partial thromboplastin time (PTT) test helps doctors assess your body’s ability to form blood clots. Each time you bleed, it triggers a series of reactions known as the “coagulation cascade.” Coagulation is the process your bod...
Coagulation tests measure your blood's ability to clot, as well as how long it takes. Testing can help your doctor assess your risk of excessive bleeding or developing clots (thrombosis) somewhere in your blood vessels.
