D-Dimer Test

Your result shows the amount of D-dimer found in your blood. If your result is higher than the normal range, it means that elevated levels of D-dimer were detected in your blood. Elevated D-dimer levels may occur when blood clots form and break down. A high result does not confirm that a blood clot is present. Many other conditions and circumstances can also cause elevated levels including age, pregnancy, infection, inflammation, recent surgery, or injury.

Your D-dimer result should be discussed with a healthcare provider who can interpret your result along with your symptoms, health history, medications, and other risk factors.

If your D-dimer result is high, you should share your result with a healthcare provider who can review it along with your symptoms, age, health history, medications, and risk factors. Depending on your overall health status, additional evaluation or imaging may be recommended.^2,3

In some clinical situations, healthcare providers use a normal D-dimer result together with a patient's symptoms, risk factors, and physical examination to help rule out certain blood clots. A D-dimer result should not be interpreted on its own and should always be discussed with a healthcare provider.

Your testing will be performed in a CLIA-certified clinical laboratory. Labcorp provides leading-edge medical laboratory tests and services through a national network of primary clinical laboratories and specialty testing laboratories. Our labs perform regular quality assurance testing to ensure our results are accurate.

Your results will be provided to you through our secure online portal to view or print. Results are also made available through a secure portal to the independent healthcare provider who placed your test order.  If you are accessing your results through your Labcorp Patient™ account, all users linked to the account will have access to all OnDemand test results. Results may also be provided to a local, state, and/or federal health authority; for example, many states require the testing laboratory and physician to report test results for certain communicable diseases, such as COVID-19, to local or state health departments.
