With a normal result, the patient is unlikely to have an acute condition or disease that leads to abnormal clot formation or breakdown.
In case of a positive result, the level of fibrin degradation product is abnormally high, which indicates excessive clot formation or degradation in the body.
Elevated D-dimer levels may indicate disseminated intravascular coagulation (a rare, life-threatening condition that prevents normal blood clotting), trauma, infection, but may also be the result of surgery. Elevated D-dimer levels may also occur in pregnancy, heart disease, liver disease, and certain types of hormones.
The test alone cannot diagnose any diseases. Determination of D-dimer level is recommended in combination with other assays. A single test is not enough to make an accurate diagnosis. In all cases, please consult the specialist or internist who ordered the test with the result.
