Clinical Significance
FDP are found at low levels in the sera of all healthy individuals because of normal firinolytic mechanisms. The mean normal level in resting adults is 4.9 ± 2.8 ug/mL. Slight elevation can occur after stress, exercise, or anxiety. Higher serum FDP levels are associated with disseminated intravascular coagulation (DIC), deep vein thrombosis, some pregnancy disorders, myocardial infaraction, and pulmonary embolism. Urine normally contains less than 0.25 ug/mL FDP. Elevated levels can appear in renal disease such as glomerulonephritis, and in acute graft rejection.
