D-Dimer Quantitative (Detects Blood Clots)


D-Dimer is one of the measurable by-products of activation of the fibrinolytic system. Quantitation of D-Dimer assesses fibrinolytic activation and intravascular thrombosis. D-Dimer is of particular value in excluding the diagnosis of venous thromboembolism among patients at high risk.

  • Fasting Required: NO
  • Preferred Specimen: Serum
  • Limitations: In patients with low or moderate probability of clots in the deep veins of the leg, a negative D-Dimer result generally rules out DVT. Some patients with blood clots will be false-negatives. This is most common among older patients, those who have undergone prolonged hospitalization, and those with markedly elevated C-reactive protein levels.
