D-dimer: A fragment produced during the degradation of a clot. The D here stands for domain. Dimer indicates two identical units, in this case two identical domains. D-dimer result from complete breakdown of the clot. Monoclonal antibody to the D-dimer fragment provide the basis for the main methods of detecting it. The presence of D-dimers in the blood is a reliable clue that clotting has begun. Sometimes written d-dimer or D-Dimer. Pronounced deemer.
Explains how the D-dimer test is used, when a D-dimer test is ordered, and what the results of a D-dimer test might mean
The d-Dimer test, which is used to rule out blood clots, is explained in this ClotCare posting.
D-dimer is a fibrin degradation product (or FDP), a small protein fragment present in the blood after a blood clot. is degraded by fibrinolysis
