What is Factor V?
Factor V is just one of the many elements that work together for proper blood clotting. If blood does not clot correctly, a patient can bleed excessively from a simple cut, let alone a more serious injury or break in the skin. 

Congenital Factor V deficiency is one type of bleeding disorder revealed with Factor V testing. Other possible causes of excessive bleeding include liver disease and fibrinolysis. Factor V is not the only factor that plays a part in the clotting process.
