Most often, hemophilia is diagnosed after a person has an abnormal bleeding episode or when there is a known family history of the condition.
|
 |
Various diagnostic tests are available to measure, under carefully controlled conditions, the length of time it takes to produce certain components of the final fibrin clot. The activated partial thromboplastin time (APTT) is performed and will ty...

The factor VIII assay is a blood test that measures the activity of factor VIII - one of the substances involved in blood clotting (coagulation.
|
|
Partial thromboplastin time (PTT) is a blood test that looks at how long it takes for blood to clot. It can help tell if you have bleeding or clotting problems.
|
|
The partial thromboplastin time (PTT) test is a blood test that is done to investigate bleeding disorders and to monitor patients taking an anticlotting drug (heparin).
|
|
A platelet count is a test to measure how many platelets you have in your blood. Platelets help the blood clot. They are smaller than red or white blood cells.
|
|
A platelet count is a diagnostic test that determines the number of platelets in the patient's blood. Platelets, which are also called thrombocytes, are small disk-shaped blood cells produced in the bone marrow and involved in the process of blood...

Prothrombin time (PT) is a blood test that measures the time it takes for the liquid portion (plasma) of your blood to clot. See also: Partial thromboplastin time (PTT)
|
 |
The prothrombin time test belongs to a group of blood tests that assess the clotting ability of blood. The test is also known as the pro time or PT test.
|
|
Hemostasis has been described as "a process by which the body spontaneously stops bleeding and maintains blood in the fluid state within the vascular compartment." There are at least four major systems that are involved in this complex process: th...

|
The factor II assay is a test to measure the activity of factor II - one of the substances involved in blood clotting (coagulation.
|
|
The factor IX assay is a blood test that measures the activity of factor IX - one of the substances involved in blood clotting (coagulation.
|
 |
Bleeding time is a blood test that looks at how fast small blood vessels close to stop you from bleeding.
|
|
Bleeding time is a crude test of hemostasis (the arrest or stopping of bleeding). It indicates how well platelets interact with blood vessel walls to form blood clots.
