[Relevant aspects of identification and interpretation of the glycated hemoglobin research findings.]

The article contains the literature review on laboratory criteria of detection and monitoring of the progression of the disease in patients with the diagnosis of diabetes mellitus. It also covers the issues of methodical approaches to the identification of glycated hemoglobin (HbA1c). The findings of author's researches of glycated hemoglobin in 149 patients have been given within the framework of comparison of two methodical approaches and comparison of the results with the subsequent classification of the received data. A random laboratory finding of qualitative hemoglobinopathy has been demonstrated, and the results recognized as unqualifiable and the approach to classification of such values have been discussed.Comparison of the results of glycated hemoglobin identification performed by different methods. 149 patients underwent a one-stage identification of glycated hemoglobin from plasma stabilized with K2-EDTA on Bio-Rad D10 and Sebia Capillarys Flex Piercing 2. Comparative study of the results of glycated hemoglobin identification has shown a difference in absolute values. However, a statistically reliable (p < 0.05) correlation between the values of glycated hemoglobin, expressed as a percentage obtained by different methods, has been revealed. In this case, the choice of a method for identifying glycated hemoglobin is not a matter of principal but it is important to adhere to the same method in treatment and long-term monitoring.
