Factor V Leiden Mutation
Factor V Leiden mutation test is ordered, along with other tests related to thrombophilia, to help diagnose the cause of venous thrombosis and/or thromboembolism (VTE). They are ordered to help determine the reason for an initial thrombotic episode, especially when it occurs in a person under 50 years old, is unprovoked, or is in an unusual place such as the liver (hepatic), the kidneys (renal), the brain (cerebral), the gut and pelvis (mesenteric), or in the eye veins. This test is used to confirm positive activated protein C Resistance (APCR) test results especially in patients with Lupus anticoagulant positivity. When the mutation is coupled with increased homocysteine levels, the risk increases manifold.
