This test measures a protein fragment (D-dimer) that is released when a blood clot breaks down. It is used to help diagnose conditions such as deep vein thrombosis (DVT) and pulmonary embolism (PE).

A D-dimer test is a blood test that checks for potential blood clotting problems by measuring a specific protein involved in blood clot breakdown.

Key Diagnostic Applications Conditions Evaluated:

• Deep vein thrombosis (DVT)
• Pulmonary embolism
• Disseminated intravascular coagulation (DIC)
• Blood clotting disorders

Test Characteristics Result Interpretation:

• Negative result: Blood clot unlikely
• Positive result: Potential blood clotting issues
• Normal level: Less than 0.50
• Positive level: 0.50 or greater

Important Considerations Factors Affecting Results: • Can be positive in: • Older individuals • Pregnant women • Recent surgery patients • Smokers • People with severe infections Limitations: • Cannot identify exact clot location • Requires additional testing for confirmation • Not a definitive diagnostic tool

The D-dimer test serves as an initial screening method for potential blood clotting complications, helping healthcare providers determine the need for further investigation.
