D-dimer

Dr Daniel J Bell and Dr Henry Smith et al.

D-dimer is a commonly tested biological marker which is produced by the enzymatic breakdown of cross-linked fibrin which forms the fibrous mesh of a blood clot. The measurement of D-dimer in the circulation acts as a marker of coagulation and fibrinolysis, which can be useful in the diagnosis of multiple diseases.
