Fibrinogen Degradation Products (FDP) Test
The Fibrinogen Degradation Products (FDP) test measures the level of fibrinogen degradation products in a frozen plasma sample. Quest describes it as a screening aid used in evaluating disseminated intravascular coagulation (DIC) and acute occlusive vascular disease.
About this test
Fibrinogen degradation products form when the clotting protein fibrinogen is broken down. This test measures their level in plasma collected in a citrate (light blue-top) tube, frozen, and analyzed using a latex agglutination method.
People who come to this test are usually already being evaluated for a clotting-related concern their clinician has identified, such as suspected DIC or an occlusive vascular event. Because Quest frames it specifically as a screening aid for those situations, the result is read together with the rest of that clinical picture rather than as a stand-alone answer.

Additional details
What this test looks at
The single value this test reports is the concentration of fibrinogen degradation products in plasma. Quest positions it specifically as a screening aid for two conditions — disseminated intravascular coagulation and acute occlusive vascular disease — rather than as a general clotting marker, so the result is most meaningful in that specific clinical context.
This test isn't part of the Celio Health store at the moment, so it can't be ordered or requested here. The test menu lists everything that can.
Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does the FDP test measure?
It measures the level of fibrinogen degradation products in plasma, using a latex agglutination method on a frozen, platelet-poor plasma sample.
How is the sample collected?
The test uses plasma collected in a citrate (light blue-top) tube, which is frozen before analysis.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Why might this test be ordered?
Quest lists it as a screening aid used in evaluating disseminated intravascular coagulation (DIC) and acute occlusive vascular disease.
