If you are getting the D-dimer test to see if treatment is working for DIC, a normal or decreasing level of D-dimer means the treatment is working. What Abnormal Results Mean A positive test means that you may be making blood clots. The test does not tell where the clots are or why you are making clots. Your provider may order other tests to see where clots are located. A positive test may be caused by other factors, and you may not have any clots. D-dimer levels can be positive due to: Pregnancy.
