Factor V Leiden Mutation Analysis
Also known as: Factor V Leiden DNA Test
Use
Contributes to the risk assessment for venous thromboembolism (VTE) to better inform decisions regarding treatment and clinical management decisions of patients with relevant personal history of VTE and potential preventative care for patients with significant family history of VTE.
Special Instructions
Genetic coordinators are available for health care providers to discuss results and for information on how to order additional testing, if desired, at 1-800-345-GENE.
Limitations
Variant analyzed: c.1601G>A (p.Arg534Gln), referred to as Factor V Leiden; NM_000130.5. Results must be combined with clinical information for the most accurate interpretation. Molecular-based testing is highly accurate, but as in any laboratory test, diagnostic errors may occur. False positive or false negative results may occur for reasons that include genetic variants, blood transfusions, bone marrow transplantation, somatic or tissue-specific mosaicism, mislabeled samples, or erroneous representation of family relationships.
