D-Dimer

D-Dimer occurs by fibrin degradation; therefore D-Dimer is used to exclude deep vein thrombosis of the leg and pulmonary embolism.

Reference Ranges

The DiaSys Cut-off value for exclusion of the deep vein thrombosis of the leg:
< 0.5 µg FEU/mL
FEU: fibrinogen equivalent units
Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.

Increased in

  1. On-going fibrinolytic process
  2. Thrombotic events such as:
    • deep vein thrombosis (DVT),
    • disseminated intravascular coagulation (DIC),
    • pulmonary embolism (PE) and- pregnancy complications
