  • D-dimer - Understand the Test - Lab Tests Online

    2021-7-20 · D-dimer is one of the protein fragments produced when a blood clot gets dissolved in the body. It is normally undetectable or detectable at a very low level unless the body is forming and breaking down blood clots. Then, its level in the blood can significantly rise. This test detects D-dimer in the blood.

    D-Dimer has increased specificity and is performed instead of FSP/FDP. May be tested from same tube as PTT however, follow PTT stricter collection and delivery guidelines. Test also performed by the Rapid Response Lab. Clinical Utility: D-Dimer <0.50 mcg/mL can be used to rule out DVT/PE in >98% outpatients with low clinical probability. D-Dimer is also useful in the diagnosis of fibrinolysis and DIC (particularly when combined with platelet count, fibrinogen level, PT, and PTT).
