Normal Reference Range:

• D-Dimer: Less than 0.5 mg/L (500 ng/mL) medicalnewstoday.com

Test Components:

• D-Dimer: A protein fragment present in the blood after a blood clot breaks down; elevated levels may indicate the presence of a blood clot my.clevelandclinic.org

Clinical Applications:

• Deep Vein Thrombosis (DVT): A condition where a blood clot forms in a deep vein, usually in the legs

• Pulmonary Embolism (PE): A blockage in one of the pulmonary arteries in the lungs, usually caused by blood clots traveling to the lungs from the legs

• Disseminated Intravascular Coagulation (DIC): A condition affecting the blood’s ability to clot and stop bleeding

Interpretation:

• Normal Result: A D-Dimer level less than 0.5 mg/L suggests the absence of significant clot formation and breakdown medicalnewstoday.com

• Elevated Result: Higher levels may indicate the presence of a blood clotting disorder; however, elevated D-Dimer levels can also be seen in conditions such as pregnancy, heart disease, recent surgery, trauma, infection, or inflammation my.clevelandclinic.org

Next Steps:

If your D-Dimer test result is elevated, your healthcare provider may recommend further testing, such as imaging studies (e.g., ultrasound, CT scan) to confirm the presence and location of a blood clot.

Always consult with your healthcare provider for a comprehensive evaluation and appropriate management based on your individual health status.
