Synonyms:
Fragment D-dimer, Fibrin degradation product
Description:
D-dimer is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. It is so named because it is comprised of two D fragments of the fibrin protein joined by a cross-link. The concentration of D-dimer may be determined by a blood test in order to help diagnose thrombosis.
