1 – Scheme overview

The target values and acceptable limits for each peer group are defined based on the previous year’s EQA schemes provided at the beginning of the year.

Each month, we externally process your IQC data (individual calculations) using the acceptable limits for trueness and imprecision.

You can enter your results (N, mean and CV only) directly on our website.

To assess serum proteins, we offer 2 serums of human origin allowing the control of proteins and protein electrophoresis.

Control samples are CE marked in accordance with European directive 98/79 EC and French law.

Samples are provided in kits of 10 vials, which once resuspended, contain 3 mL of serum.
