D-Dimer Test

This test measures the amount of D-dimer (one of the products produced when blood clots disolve). This test is used to diagnose problems such as DIC which stands for disseminated intravascular coagulation. DIC is an abnormal condition where clots begin to form throughout the body. It also helps evaluate conditions such as deep vein thrombosis (DVT), sickle-cell anemia, and clotting during pregnancy. It is usually increased in any disease or problem in which there is increased clotting taking place in the body.

PREPARATION FOR TEST

No preparation or fasting is necessary.

NORMAL FINDINGS

  • Quantitative: less than 250 ng/mL or less than 250 mcg/L (SI units)

Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.
