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.

These samples are not compatible with the method measuring RBC aggregation capacity by optical density ALIFAX (ROLLER 10, ROLLER 20, JO-PLUS and TEST1) and ALCOR Scientific (iSED and miniiSED).
