What Is a D Dimer Blood Test For

D-dimer tests are used to check for blood clotting problems. Blood clots can cause health problems, such as: Deep vein thrombosis (DVT) Pulmonary embolism (PE)

What does it mean when your D-dimer is elevated?

What does a high D-dimer test result mean? If your results reveal that you have higher-than-normal levels of D-dimer in your blood, it may mean that you have a blood clotting condition. A D-dimer test can’t determine the type of blood clotting condition you may have or where the blood clot(s) is in your body.

What is the D-dimer normal range?

A normal D-dimer is considered less than 0.50. A positive D-dimer is 0.50 or greater. Since this is a screening test, a positive D-Dimer is a positive screen.
