D-dimer testing is ordered primarily to assess for the presence of what?

• A. Blood clots or DIC
• B. Dehydration
• C. Infections
• D. Anemia

Answer: (A)

D-dimer testing is used to detect evidence of abnormal clot formation and breakdown in the body. When a clot forms, fibrin is laid down in the clot and, as the clot is dissolved, fragments of fibrin called D-dimer are released into the blood. A positive result suggests recent or ongoing clotting activity, which helps diagnose conditions such as blood clots (like deep vein thrombosis or pulmonary embolism) and disseminated intravascular coagulation. It isn’t a test for dehydration, infections, or anemia, which aren’t primarily about clot formation and breakdown. Keep in mind that D-dimer can be elevated for other reasons too, so results must be interpreted with clinical context.
