Factor VIII Activity Blood Test, Clotting
A Factor VIII Activity Blood Test is useful in measuring the activity of factor VIII, a blood-clotting protein.
This test can aid in the diagnosis of hemophilia A or another clotting disorder. Hemophilia A, the most common type of bleeding disorder, causes the blood not to clot as it should. This, in turn, puts someone susceptible to uncontrolled bleeding. Most commonly, this disorder is found in males.
One might order this test if they have the following symptoms:
- Sustained bleeding after minor cuts, surgeries, or dental procedures
- Easily bruised
- Severe low back pain, generally on one side
- Joint pain or stiffness
- Slow wound healing due to repeated bleeding or infection
- If a blood transfusion was needed after minor surgery
The partial thromboplastin time (PTT) and prothrombin time (PT) is another useful test for hemophilia.

The fibrinogen antigen blood test is used in the diagnosis of homozygous and heterozygous fibrinogen deficiency as well as dysfibrinogenemia; diagnosis of disseminated intravascular coagulation; fibrinogen levels can be used to assess the effectiveness of thrombolytic therapy.

The Prothrombin Time (PT) w/ INR and Partial Thromboplastin Time (PTT) Blood Test helps detect and diagnose a bleeding or excessive clotting disorder.
