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

The verification of analytical methods is crucial to ensure the accuracy of results. This study evaluates the performance of the microalbuminuria assay method in the central laboratory of CHU Mohammed VI in Oujda, to confirm its reliability for the diagnosis and monitoring of renal disorders and related conditions. We conducted a performance study of the Alinity ci® system by assessing repeatability and reproducibility in accordance with the COFRAC GTA 04 technical accreditation guidelines, in line with the quality requirements of the ISO 15189 standard. The results of our study indicate satisfactory repeatability for the two levels (low and high), with coefficients of variation of 1.24% and 1.12%, respectively. Additionally, reproducibility was also satisfactory, with coefficients of variation for these same levels of 4.73% and 4.75%, respectively. The reliability of the microalbuminuria assay results in our laboratory is confirmed by the satisfactory results obtained in our study, which comply with the recommendations of RICOS and FSCB.
