This test detects D-Dimer, a protein fragment produced when a blood clot dissolves.

Diagnostic Value: Elevated levels indicate recent or ongoing clot formation and breakdown, seen in DVT, PE, or disseminated intravascular coagulation (DIC).

Clinical Significance: Often used as a screening tool to rule out thrombotic events; a normal result makes acute thrombosis unlikely.

Symptom Correlation: High levels may be found in patients with leg swelling, chest pain, or shortness of breath due to clot formation.

The D-Dimer test is a key marker for detecting abnormal clotting and monitoring treatment response.
