Why It’s Done
This test is typically ordered to:
• Diagnose Factor V deficiency, a rare bleeding disorder that can cause excessive bleeding.
• Evaluate unexplained prolonged bleeding or abnormal clotting test results (such as prolonged PT or aPTT).
• Monitor liver function since Factor V is produced in the liver, and low levels may indicate liver disease.
• Investigate abnormal clotting conditions in combination with other coagulation tests.
• Differentiate between inherited and acquired bleeding disorders.
Preparation
• No special preparation is required.
• Inform your doctor of any medications you’re taking, especially blood thinners, aspirin, or hormone therapy, as they can affect clotting results.
• If you have a bleeding or clotting history, mention it to the healthcare provider collecting the sample.
