D‑Dimer, Quantitative
Use
The D‑Dimer test is frequently used to help exclude an acute pulmonary embolism (PE) or deep vein thrombosis (DVT). In patients with a low to moderate clinical risk assessment and a D‑Dimer result below the cutoff (0.50 µg/mL FEU), the likelihood of PE or DVT is very low. Elevated D‑Dimer levels may be associated with PE, DVT, disseminated intravascular coagulation (DIC), malignancies, inflammation, sepsis, surgery, trauma, pregnancy, and advancing age.
