Monitoring of glycemic balance by glycated hemoglobin assay on D-10^® (Biorad) and Minicap Flex Piercing^® (Sebia) biochemical systems at the Rodolph-Mérieux Laboratory in Bamako

This study aims to determine the concordance of results between D-10® and Minicap Flex Piercing® and the impact of the presence of hemoglobin variants in the glycated hemoglobin assay. All the samples were assayed in parallel. The agreement between these methods was assessed using the Bland and Altman plot. We collected a total of 166 samples. In the entire study population and in patients with a hemoglobin variant, the Bland and Altman graph showed good agreement between the values (for respective biases of 0.21% and 0.29%) as well as a significant correlation (p < 0.001). Our results differ from those found by Kesso Barry et al. This difference can be explained by the high prevalence of patients with abnormal hemoglobins S and C (39.2 %) in our study population. Despite a good agreement between the methods, the results do not allow us to confirm a transferability between the two systems in diabetics and carriers of hemoglobin variants.
