Factor V Leiden Mutation
This Test is a molecular diagnostic test used to detect a specific genetic mutation in the Factor V gene. This mutation increases the risk of abnormal blood clot formation (thrombosis).
Individuals with this mutation may have a higher risk of conditions such as deep vein thrombosis (DVT) or pulmonary embolism (PE). The test is commonly recommended for people with a history of unexplained blood clots, recurrent pregnancy loss, or a family history of clotting disorders.
The purpose of the test is to:
- Detect the Factor V Leiden genetic mutation
- Assess risk of abnormal blood clotting
- Help diagnose inherited thrombophilia
- Support prevention and management of clotting disorders
FACTOR V LEIDEN MUTATION Test
The Factor V Leiden Mutation test detects a specific inherited change in the F5 gene that makes factor V less responsive to activated protein C, a natural anticoagulant in the body. This condition is known as Factor V Leiden thrombophilia.
The mutation can increase a person's tendency to develop venous blood clots, particularly deep vein thrombosis (DVT) and pulmonary embolism (PE). The risk varies depending on whether a person has one or two copies of the mutation and other factors such as age, surgery, immobility, pregnancy, and certain medications.
This genetic test can help identify an inherited predisposition to thrombosis. A positive result does not mean that a person will definitely develop a blood clot, and results should be interpreted along with personal and family history and other risk factors.
FACTOR V LEIDEN MUTATION Test is Recommended for Individuals:
- Individuals with unexplained or recurrent venous blood clots
- People who develop DVT or pulmonary embolism at a relatively young age
- Individuals with a strong family history of thrombosis
- Patients with recurrent blood-clotting episodes without an obvious cause
- Individuals being evaluated for an inherited thrombophilia
- Selected patients with thrombosis associated with pregnancy or estrogen exposure, when clinically indicated
- Family members of individuals with a confirmed Factor V Leiden mutation, when testing is recommended
FAQs
1. What does the Factor V Leiden Mutation test detect?
It detects the Factor V Leiden genetic variant in the F5 gene, which can increase the tendency to form abnormal blood clots in veins.
2. Does a positive Factor V Leiden result mean I will develop a blood clot?
No. A positive result indicates an increased genetic risk, but it does not mean a blood clot will definitely occur. Other factors can significantly influence an individual's overall risk.
3. Is Factor V Leiden inherited?
Yes. The mutation is inherited from a parent. A person may have one copy (heterozygous) or two copies (homozygous), and the associated clotting risk can differ between these situations.
