Expert Biologists - Scheme Coordinators:
Estelle BUGNI and Laurent JALLADES
EQA performed since 2012
Number of participating laboratories in 2022: 245

1 – Scheme overview

This scheme is designed to assess different automated or manual methods used to determine the sedimentation rate. The interpretation of the results obtained for each concentration level is supported by a graphical display of the accuracy using a Youden plot.

Panneau attention This program is not compatible with the method measuring RBC aggregation capacity by optical density of Beckman Coulter (ALIFAX / ROLLER 10, ROLLER 20) and ALCOR Scientific (i-SED).

2 – Assessment frequency
