Factor V of Leiden

Factor V of Leiden


The Factor V Leiden test is a genetic test that detects a specific mutation in the Factor V gene, which affects normal blood clotting. This mutation can increase the likelihood of developing conditions such as deep vein thrombosis (DVT) or pulmonary embolism. The test is often recommended if you have experienced unexplained blood clots, recurrent pregnancy complications, or have a family history of clotting disorders.
