Summary
The Factor V test is a blood test that measures the amount or function of Factor V, a protein involved in blood clotting. It helps diagnose bleeding disorders or clotting abnormalities.

- Blood clots in veins or arteries.
- Family history of bleeding disorders.
- Recurrent miscarriages.
Preparation
