<0.50 mg/L Fibrinogen Equivalent Units (FEU)
D-dimer units of measurement are mg/L FEU, where FEU = fibrinogen equivalent units. In conjunction with a non-high clinical probability assessment, a D-dimer result below the accepted cut-off (< 0.5 mg/L FEU) excludes deep vein thrombosis and pulmonary embolism with high sensitivity. D-dimer values above the reference range (> 1.14 mg/L FEU) are not specific and may be seen in deep venous thrombosis, pulmonary embolism, disseminated intravascular coagulation, fibrinolysis, recent surgery, active bleeding, hematomas, trauma, pregnancy, liver disease, inflammation, and malignancy.
