Factor V Leiden Mutation Test

The Factor V Leiden test is a genetic test aimed at detecting a mutation in the gene responsible for producing Factor V, a clotting factor. This mutation increases the risk of abnormal blood clots, such as deep vein thrombosis (DVT) or pulmonary embolism. The test is typically performed for individuals with a personal or family history of recurrent clots or during pregnancy. Positive results indicate the presence of the mutation, which increases the likelihood of clotting, while negative results rule out the mutation.
