The ‘D’ denotes to domain, and the dimer shows two identical units, D dimer means two identical domains. The presence of D dimer in the blood shows the process of blood clotting. D dimer is detected in a blood through monoclonal antibody. The D dimer also serves as a marker for pulmonary embolism or deep vein thrombosis.

What is the D-dimer test?

D-dimer test measures the amount of D dimer in the blood, which is usually at extremely low levels and is hard to detect in the blood. If you test positive for this test, it means you have high levels of D dimer in the blood.

D-dimer test is one way to find out a serious blood clot or monitoring blood clotting problems in the body. D-dimer test along with other imaging tests plays a vital role in the diagnosis of thrombotic disorder; a positive test result shows thrombosis and other probable causes and negative test results rules out thrombosis. D dimer test also plays a significant role in the diagnosis of blood disorders as disseminated intravascular coagulation.

• Coughing with blood
• Rapid heartbeat
• Chest pain
• Sweating
• Fainting

D Dimer test result

If the D-dimer test results come positive, then it means that the individual has blood clots in the body and higher than normal D-dimer levels show to a significant amount of blood clot. A positive D-dimer test results, however, do not point out the location of the blood clot and other screening tests might be required.
