D-dimer (or D dimer) is a dimer that is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. It is so named because it contains two D fragments of the fibrin protein joined by a cross-link , hence forming a protein dimer .
D-dimer is highly sensitive but not specific (specificity around 50%). In other words, a positive D-dimer is not synonymous with PE, but a negative D-dimer is, with a good degree of certainty, an indication of absence of a PE. [52] A low pretest probability is also valuable in ruling out PE. [53]

Principles of D-dimer testing. Fibrin degradation products (FDPs), also known as fibrin split products, are components of the blood produced by clot degeneration. [1] Clotting, also called coagulation, at the wound site produces a mass of fibrin threads called a net that remains in place until the cut is healed. As a cut heals, the clotting ...
