D-DIMER Detail

D-Dimer is a small protein fragment that is produced when a blood clot dissolves in the body. The D-Dimer test is a valuable diagnostic tool to detect active clot formation and breakdown in the bloodstream.

Under normal circumstances, D-Dimer is undetectable or present at very low levels. When the body forms and breaks down blood clots excessively, D-Dimer levels increase.

Clinical Use:

The D-Dimer test is primarily used to help rule out thrombotic conditions such as:

• Deep Vein Thrombosis (DVT) – blood clots in deep veins, usually in the legs,

• Pulmonary Embolism (PE) – a clot in the lungs,

• Disseminated Intravascular Coagulation (DIC) – a serious condition causing widespread clotting and bleeding,

• Stroke or other clotting disorders,

• Monitoring coagulation status in COVID-19 or post-surgery patients.
