What is Factor VIII?
The clotting system of the human body is a complex process. Several Factors, including Factor VIII, play an important part in blood clotting. When any one of the Factors is not being produced at healthy levels, the clotting process can be impaired. Factor VIII is specifically associated with Von Willebrand’s disease and hemophilia type A. Other causes for higher than normal Factor VIII values include age, disease of the liver, pregnancy, diabetes and inflammation.
