Verification of glucose assessment analytical method
 ILLEOVÁ, Kateřina
The topic of laboratory accreditation as well as validation and verification of analytical methods has been very current in recent years. Because of the serious impact of analytical results of the measurement on practice, it is required that the results of the analytical measurements were as accurate as possible. This paper deals with the verification of the analytical method determination of glucose, as proof of achieving optimum measurement uncertainties. The verification of spectrofotometric glucose determination was performed using the Cobas Integra 800 analyzer by enzymatic hexokinase method. For the measurement in time the control materials of internal quality control were used and for the measurement in series the control materials of external quality control were used. From the measured values we specified the necessary statistical data (the arithmetic mean, standard deviation, the coefficient of variation, bias, yield) and using these we specified the values of combined and extended uncertainty. The combined uncertainties of both samples shouldn't be higher than 10 %, according to the SEKK association. The combined uncertainty of our first sample was 6.81 % and the second one had 6.45 %. The extended uncertainty of the first sample was 13.62 % and the second one had 12.90 %. From these data, we can conclude that the verification of analytical methods for the determination of glucose succeeded.
