Quantification of intrinsic Coagulation Factor VIIIc, by automatic machine **

The Factor IX test is primarily used to diagnose hemophilia B, assess Factor IX deficiency, monitor treatment effectiveness, and support the diagnosis of blood clotting disorders.

The Factor XI test is primarily used to diagnose Factor XI deficiency (Hemophilia C), assess bleeding risk, monitor treatment, and support the diagnosis of other blood clotting disorders

Factor X is a clotting protein (also called a clotting factor). Clotting factors are specialized proteins that are essential for proper clotting, the process by which blood clumps together to plug the site of a wound to stop bleeding. Clotting requires a series of reactions to ultimately form a clot to plug a wound.
The factor X assay is a blood test to measure the activity of factor X

. Fibrinogen is a protein in the body called a clotting factor. Clotting factors combine to form a blood clot, which helps stop bleeding when the body’s tissues or blood vessels are damaged.
. Fibrinogen testing is used to evaluate and monitor symptoms such as difficult-to-stop bleeding or abnormal blockages (clots) in blood vessels. It detects increased or decreased levels of fibrinogen (factor I) that may be acquired or congenital and monitors the severity of treatment for disseminated intravascular coagulation and fibrinolysis.

A “Factor VIII inhibiting antibody screening test”, also known as a “Factor VIII inhibitor screen”, is a blood test used to detect the presence of antibodies in a patient’s plasma that can neutralize Factor VIII, a crucial protein involved in blood clotting, essentially indicating a potential bleeding disorder related to hemophilia A
