Fibrinogen Degradation Product

Fibrinogen or fibrinogen degradation products (FDP) are the substances found in the bloodstream after a blood clot has dissolved. Fibrin is a protein. It helps in clotting. When a blood clot and fibrin dissolve, particles of fibrin are released in the body. These particles are fibrinogen degradation products. An FDP test determines the level of FDP to check for a clotting disorder. It is also ordered to check for deep vein thrombosis, kidney disease, leukemia, stroke, and pulmonary embolism or blockage in the main artery of the lungs.

It’s a simple blood test with minimal risks. Inform the doctor if you are on such drugs as barbiturates, heparin or any medication to dissolve blood clots. These could affect the test and increase FDP levels.
