Factor 5 (V) Leiden Test
Description:
Factor 5 (V) Leiden Test
The Factor V Leiden test looks for a genetic mutation that is commonly associated with an increased risk of abnormal blood clots or thrombosis. Factor V is a protein that plays an important role in hemostasis, the process by which the body stops bleeding when an injury occurs. Factor V Leiden is an inherited mutation that may cause excessive clotting. These irregular blood clots can block veins causing serious health concerns. Factor V Leiden is the most common inherited clotting disorder, affecting 3-8% of people in the U.S. However, not all people with the Factor V Leiden mutation will develop irregular blood clots. About 10% of those affected will have one or more thrombotic episodes.
This test is typically ordered when a person has had one or more unexplained blood clots, especially during pregnancy. It may also be ordered as a preemptive screening for someone who has a family history of clotting disorders.
The Current turnaround for the Factor V Blood Test is typically 10-17 business days.
