A Factor V Leiden test assesses the presence and impact of a specific genetic mutation that can increase the risk of blood clots. Typical laboratory reports provide both normalized ratios and percentages, often comparing an individual’s clotting time to a standard. These values assist healthcare professionals in determining if a patient possesses the Factor V Leiden mutation and, if so, whether it’s heterozygous (one copy of the mutated gene) or homozygous (two copies).
Understanding an individual’s predisposition to thrombosis is crucial for preventative care. Elevated values, indicative of the mutation’s presence, inform critical decisions regarding anticoagulation therapy and lifestyle adjustments. Historically, diagnosing this genetic predisposition was challenging, but contemporary testing allows for targeted interventions and risk mitigation strategies. This knowledge empowers both patients and physicians to proactively manage potential thrombotic events, potentially preventing serious complications like deep vein thrombosis and pulmonary embolism.
