Abstract:
The verification of analytical methods is essential to ensure the accuracy of results. This study evaluates the performance of the transferrin assay method in the central laboratory of CHU Mohammed VI in Oujda, in order to confirm its reliability for the diagnosis and monitoring of iron metabolism disorders.
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 three levels (low, medium, and high), with coefficients of variation of 1.64%, 1.13%, and 1.10%, respectively. Additionally, reproducibility was also satisfactory, with coefficients of variation for these same levels of 2.88%, 2.65%, and 3.30%, respectively.
The reliability of transferrin assay results in our laboratory is confirmed by the satisfactory results obtained in our study, which comply with the recommendations of RICOS and FSCB.
