|EQA 2023 - Immunoassay (CIPO)|
Expert Biologists - Scheme Coordinators:
Laurence CHARDON and Marie LOPEZ
EQA performed since 1977
Number of participating laboratories in 2022: 860
1 - Scheme Overview
This external quality assessment allows the control of immunoassays with hormone markers and tumor or metabolic markers. This scheme brings together 60 analytes distributed over 11 sub-schemes.
The most commonly assayed analytes are offered in the CIMD scheme. The more specialized analytes are offered in the CIMA, CIMB, CIME, CIMF, CIMG, CIMH, CIMN, CIMR, CIMT and CIMV programs (see Table below).
The determination of the acceptable limits is based on the use of biological variations.
Participating labs can choose to be assessed for all the analytes of this scheme, or simply a subset of analytes of interest.
2 - Assessment Frequency
Number of surveys per year: 6
Number of control samples per survey: 2
Number of samples per year: 12 (except for the CIMG scheme: 9 samples)

4 - Description of the Control Samples
Lyophilized human control serum (with the exception of CIMG samples for Glucagon) . The samples are to be resuspended in :
|For the CIMD sub-scheme, we advise laboratories testing more than 18 analytes to order an additional kit.|
