D-Dimers

When a fibrin clot forms in the body it is normally broken down and removed by the fibrinolytic pathway. D-Dimers are generated when cross-linked fibrin is broken down by this pathway. They are a specific breakdown product from a blood clot. D-Dimers are useful in 2 circumstances:1. They act as a negative predicitive indicator of a VTE of PE. 2. They can be used in diagnosis of DIC
