What is a Coagulation Screen?

The Coagulation screen is used in many scenarios including as a pre-operative screen to assess bleeding risk, monitor bleeding conditions and some therapies, and also to assess patients demonstrating a bleeding/bruising history or a thrombosis history or that have a family history of bleeding/bruising.

What can I test?

Prothrombin Time

The international normalised ratio (INR) is a laboratory measurement of how long it takes for blood to form a clot. This can be useful to be able to determine the effects of anticoagulants such as warfarin on the clotting system.

Fibrinogen

A fibrinogen activity test is also known as a Factor I Activity. It’s used to determine the level of fibrinogen in your blood. Fibrinogen, or factor I, is a blood plasma protein that’s made in the liver. Fibrinogen is one of 13 coagulation factors responsible for normal blood clotting. When you start to bleed, your body initiates a process called the coagulation cascade, or clotting cascade. This process causes coagulation factors to combine and produce a clot that’ll stop the bleeding. If you don’t have enough fibrinogen or if the cascade isn’t working normally, clots will have difficulty forming. This can cause excessive bleeding.

APTT Ratio

APTT, or Activated Partial Thromboplastin Time measures the speed at which blood clots in the body are formed, through a route known as the intrinsic pathway.
