Fibrin degradation products blood test

Definition

Fibrin degradation products (FDPs) are the substances left behind when clots dissolve in the blood. A blood test can be done to measure these products.

How the Test is Performed

A blood sample is needed.

How to Prepare for the Test

Certain medicines can change blood test results.

How the Test will Feel

When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or slight bruising. This soon goes away.

Why the Test is Performed

This test is done to see if your clot-dissolving (fibrinolytic) system is working properly. Your provider may order this test if you have signs of disseminated intravascular coagulation (DIC) or another clot-dissolving disorder.

Normal Results

The result is normally less than 10 mcg/mL (10 mg/L).

Note: Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different specimens. Talk to your provider about the meaning of your specific test results.

What Abnormal Results Mean

Increased FDPs may be a sign of primary or secondary fibrinolysis (clot-dissolving activity) due to a variety of causes, including:

Risks

There is little risk involved with having your blood taken. Veins and arteries vary in size from one person to another, and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

Other risks with having blood drawn are slight, but may include:
