D-Dimer Quantitative
₹1,000.00
Description
- Definition: The D-Dimer Quantitative test measures the levels of D-dimer, a fibrin degradation product found in the blood after a blood clot dissolves. Elevated levels can indicate the presence of abnormal clotting.
- Purpose: This test is primarily used to help diagnose or rule out thromboembolic disorders, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). It is often part of the workup for patients presenting with symptoms of these conditions.
- Clinical Relevance: D-Dimer testing is valuable in emergency settings, as it can aid in the evaluation of patients with acute chest pain or leg swelling. However, elevated D-Dimer levels are not specific to thrombosis and can be influenced by other factors, such as infections or inflammation.
- Interpretation: Normal D-Dimer levels are typically less than 500 ng/mL (or <0.5 μg/mL). Elevated levels may suggest the presence of a thrombus but require further evaluation and clinical correlation to confirm a diagnosis. Very high levels can indicate a higher likelihood of clotting disorders.
- Testing Method: The test involves a blood sample drawn from a vein, which is then analyzed in a laboratory using techniques such as enzyme-linked immunosorbent assay (ELISA) or latex agglutination. Results are usually available within a few hours, assisting in timely clinical decision-making.
