Verification of analytical performance of Carcinoembryonic antigen assay on the Abbott Alinity ci®: Experience of the central laboratory of Mohammed VI University Hospital of Oujda

The aim of our study was the verification of the analytical performance of Carcinoembryonic antigen determination on the Abbott CI analyzer utilizing the immuno-chemiluminescence method. The verification process was conducted in the biochemistry laboratory of Mohammed VI University Hospital of Oujda. The working methodology adapted is based on the recommendations of the protocol of the French accreditation committee (COFRAC) accreditation technical guide (GTA) 04, by the evaluation of reproducibility and repeatability. The results obtained by this evaluation were overall satisfactory and have meet the recommended criteria set by supplier and the French society of clinical biology.
