July 3, 2023The Von Willebrand Factor (VWF) blood test measures the level and activity of Von Willebrand Factor, a protein involved in blood clotting. Von Willebrand Factor helps platelets stick together and adhere to damaged blood vessel walls, promoting clot formation.
Sample Type: The test requires a small blood sample, typically obtained by drawing blood from a vein in your arm using a needle.
Normal Range: The normal range for Von Willebrand Factor levels can vary depending on the specific laboratory and the reference values they use. Generally, the normal range is around 50% to 150% activity.
Von Willebrand Factor deficiencies or abnormalities can lead to a bleeding disorder called Von Willebrand disease. This inherited condition affects the ability of blood to clot properly and can result in prolonged bleeding after injuries, nosebleeds, or heavy menstrual bleeding in affected individuals.
The Von Willebrand Factor blood test measures the level and activity of Von Willebrand Factor to assess its functioning in the clotting process. If the level or activity of Von Willebrand Factor is below the normal range, it may indicate a deficiency or abnormality, and further evaluation may be needed to determine the specific type of Von Willebrand disease and appropriate management.
It’s important to consult with a healthcare professional for proper interpretation of your Von Willebrand Factor test results and to discuss any necessary steps or treatments based on the findings, especially if you have a personal or family history of bleeding disorders.
