Introduction. The COVID-19 pandemic has ushered in many economic, psychological, social, health shocks and other consequences around the world. One of them is the accelerated aging of the population. Scientific evidence from the literature suggests that blood glucose levels increase with age and hyperglycemia contributes to the development of accelerated aging. Purpose of the study: to determine the concentration of glucose and fructosamine in the blood of people during the pre-Covid, Covid and post-Covid periods in the context of accelerated aging. Materials and methods. Primary data of laboratory test results were downloaded from the laboratory information system of the module “Laboratory NLab” of the Medical Information System “Ariadna” of State Medical Public Hospital № 2. 15,000 and 428 results of analysis of glucose and fructosamineconcentrations, respectively, in the blood of patients over 18 years of age were analyzed. In each of the samples there was a distribution of test results by study periods: pre-Covid period (09/01/2019 - 12/31/2019), Covid period - only for glucose (11/11/2020 - 02/21/2021), post-Covid period (09/01/2022 - 12/21/2022 ). Results and discussion. The results of the study showed an increase in blood glucose concentration during the covid period (from 5.9 to 6.9 mmol/l, p
