Introduction : the verification/validation of a technique consists in evaluating the performance of the analytical process, quantifying them according to a standardized operating procedure and then judging them according to defined criteria. We evaluated the analytical performances of the analyzer using ion-exchange HPLC for the measurement of HbA1c.Materials and methods : based on the recommendations of Valtec protocol and the technical guide for accreditation in Human Health, edited by the COFRAC we evaluated the analytical performance of the analyzers. Data was analyzed using Microsoft Office Excel, VDM softwares and SPSS V10 at 5 % risk.Results : repeatability and intermediate fidelity were satisfactory with CV values of 0.338 % and 1.25 % respectively for the mean level (HbA1c = 5.4 %) and 0.17 % and 4.09 % for the high level (HbA1c = 10.7 %). The accuracy was derived from the EEQ results by calculating the bias and showing compliance with the target values. Linearity is sufficient in the context of use. The measurement uncertainty approach and the inter-sample contamination were found to be satisfactory for routine use.Conclusion : from our study results, the verified analyser presents the analytical performance required for a determination of HbA1c in a reliably way.
