Factor V Activity

This test measures Factor V, a protein that supports thrombin generation in the clotting cascade.

Diagnostic Value: Low activity may indicate Factor V deficiency, leading to bleeding disorders, while resistance to activated Protein C (Factor V Leiden) increases clotting risk.

Clinical Significance: Helps diagnose bleeding tendencies or inherited thrombophilia.

Symptom Correlation: Patients may experience nosebleeds, prolonged bleeding, or deep vein thrombosis.

The Factor V Activity test helps identify both bleeding and hypercoagulable conditions.
