Coagulation Factor Assays | CF Assays |

Coagulation factor tests are blood tests that check the function of one or more of your coagulation factors.


Coagulation factors are proteins in the blood that help control bleeding. You have several different coagulation factors in your blood. When you get a cut or other injury that causes bleeding, your coagulation factors work together to form a blood clot. The clot stops you from losing too much blood. This process is called the coagulation cascade.

Some Coagulation factors are mentioned, there are others also...

by number (Factor I, Factor II, Factor VIII, etc.) or by name (fibrinogen, prothrombin, hemophilia A, hemophilia B, etc.

What is it used for?
A coagulation factor test is used to find out if you have a problem with any of your coagulation factors. If a problem is found, you likely have a condition known as a bleeding disorder

Why do I need a coagulation factor test?

You may need this test if you have a family history of bleeding disorders.
Most bleeding disorders are inherited.

You may also need this test if you have a bleeding disorder that is not inherited.

Although uncommon, other causes of bleeding disorders include:

Liver disease
Vitamin K deficiency
Blood-thinning medicines

In addition, you may need a coagulation factor test if you have symptoms of a bleeding disorder. These include:

Heavy bleeding after an injury
Easy bruising
Swelling
Pain and stiffness
An unexplained blood clot
