Interpretive Data
The presence of rheumatoid factor may lead to false-positive results with the D-Dimer test. This test should not be used to rule out venous thromboembolism.
Maximal values less than 10 µg/mL FEU are rarely indicative of DIC.
Results are reported in Fibrinogen Equivalent Units (FEU).
