Tests & Treatments for Bleeding Disorders and Hemophilia

Tests for Bleeding Disorders

Complete Blood Count

Your doctor may order a complete blood count (CBC) to determine the number of platelets, which are key clotting factors, in the blood. A low platelet count may be an indication of a bleeding disorder.

Prothrombin Time

The prothrombin time (PT) blood test shows whether or not important clotting factors are present in the blood. The test also measures the time it takes blood to clot. The PT test can reveal hemophilia or other blood disorders, as well as poor liver function.

Partial Thromboplastin Time

The partial thromboplastin time (PTT) is another blood test that measures the time that it takes blood to clot.

Factor VIII Assay

The Factor VIII assay blood test measures the function of a specific protein (Factor VIII) used to help blood to clot. Low levels of this protein may be a sign of bleeding disorders, liver disease and other conditions.

Von Willebrand Factor

This test measures the presence and function of von Willebrand factor, a protein that helps platelets to plug damaged blood vessels. Von Willebrand factor also carries the Factor VIII protein through the bloodstream.

Bleeding Disorders and Hemophilia Treatments

Treatments for bleeding disorders include:

• Hormones that increase the amount of clotting factors in the blood or cause the body to release clotting factors
• Drugs that prevent clots from breaking down
• Injections of plasma (the liquid part of blood) into the blood. Injections of concentrates containing clotting factors may also be used
