The main marketed reagents are represented: quantitative automated methods and manual methods (screening and semi-quantitative testing of FDPs).

3 levels of concentration are tested.

Statistical reports are sent with supporting comments from the expert clinical biologists who coordinate the scheme.

2 – Assessment frequency
