This test evaluates Factor VII, a key protein in the extrinsic pathway of coagulation.

Diagnostic Value: Low levels cause prolonged PT and can result from vitamin K deficiency, liver disease, or congenital Factor VII deficiency.

The Factor VII Activity test is essential for assessing clotting function in the early steps of coagulation.
