The analytical quality and comparability value of four glucometers from different manufacturers
The modern laboratory medicine provides observation of requirements to glucometers in line with standard DIN EN ISO 151972:2013 for self-control under treatment of patients with diabetes mellitus and registration of biologic types data. The study compared functioning of diagnostic devices in point-of-care of four manufacturers. The samples of whole blood taken from two patients were analyzed in three lots of test-strips with concentration of glucose 4.5 and 11.8 mmol/l using glucometers Accu-Chek Active, One Touch Select, Sattelite Express and Contour TS and reference analyzer Olympus AU 400. The results of measurements were analyzed using technique of separated test ofpatient. The results demonstrated that precision indicators of measurement of blood glucose on glucometers Accu-Chek Active and One Touch Select were within the scope of quality criteria DIN EN ISO 151972:2013. The results of testing of glucometer Sattelite Express exceeded the given criteria under measurement of normoglycemic level of concentration and for Contour TS in all range of measured values.
