What is Factor VII?
Factor VII aids the blood clotting process. There are several factors used in healthy clotting. Low or high levels of one or more of the factors can cause excessive bleeding and increase the risk of death from injury.
A Factor VII Assay will be ordered with other factor assays to determine the cause of excess bleeding. A congenital disorder known as Factor VII Deficiency can cause the clotting disorder. Other potential causes include deficient Vitamin K levels, cirrhosis and malabsorption of fat.
