Sažetak

Aim: We aimed to evaluate Accu Chek Compact Plus blood glucometer by comparing its accuracy and precision with laboratory reference system.
Methods: Original Olympus Glucose reagent on Olympus AU 2700 analyzer served as a reference method. The difference between Olympus and Accu Chek glucose concentrations was tested by paired t-test. Glucometer accuracy was evaluated using: bias (%), Passing-Bablock regression, Bland-Altman and Clarke Error Grid analysis. Intra-assay glucometer precision was examined by 10 consecutive measurements at three glucose levels.
Results: The average bias of Accu Chek was -6.6%; Passing-Bablock analysis revealed that there was no significant deviation from linearity; as of Bland-Altman analysis more than 95% of our values lied between mean ± 1.96 SD. The results of the Clarke Error Grid analysis were 100% in zone A of the error grid.
Conclusions: Accu Chek Compact Plus blood glucometer has a good accuracy and precision compared with our laboratory referent-sistem and may be used for daily blood glucose self monitoring.
