Factor V Leiden Mutation Analysis Blood Test
The factor V Leiden mutation analysis blood test is used to detect a genetic mutation in the factor V gene, causing an increased risk of thrombosis or abnormal blood clots.
Factor V Leiden is a blood clotting factor that has been mutated. This mutation raises the risk of abnormal blood clots, which most often occur in your legs or lungs. The majority of people who have factor V Leiden never get abnormal clots. However, in those who do, these rare clots may cause long-term health issues or even death.
The factor V Leiden mutation does not cause any symptoms in and of itself. Since factor V Leiden puts an individual at risk for blood clots in the legs or lungs, an abnormal blood clot may be the first sign that you have the condition.
Deep vein thrombosis (DVT) is a clot in a deep vein that most commonly affects the legs. A DVT does not show any signs or symptoms. If signs and symptoms do appear, they can include the following:

- Chest pain when breathing in
- Sudden shortness of breath
- Couth that produces bloody sputum
