Accuracy Evaluation of Five Blood Glucose Monitoring Systems in Patients from Different Departments

Abstract

Self-monitoring of blood glucose (SMBG) systems are expected to be accurate and provide reliable results. The international standard ISO (International Organization for Standardization) 15197:2013 is widely accepted for the accuracy evaluation for SMBG systems. Accuracy evaluation was performed for 5 different SMBG systems in patients from multi-departments at the hospital. A total of 120 patients from Changzhou Second People's Hospital (Changzhou, China) were randomized and enrolled in the study. Accuracy evaluation was performed for 5 different SMBG systems: Gold AQ (Sinocare), Freestyle Optium Xceed (Abbott), Contour TS (Bayer), OneTouch Ultra (J&J) and Accu-Chek Performa (Roche). For each system, comparison measurements were performed with YSI 2300 STAT PLUS Glucose and Lactate Analyzer and Roche Cobas 8000 Modular Analyzer. All 5 systems showed that 100% of results fall within consensus error grid Zones A and B. Compared with YSI 2300 or Roche Cobas 8000 Modular Analyzer, Gold AQ system showed the highest accuracy. The linearity analysis also showed that Gold AQ had the highest correlation coefficient. Compared with other SMBG systems, Gold AQ Glucose Monitoring System manufactured by Sinocare Inc. had the highest accuracy in measuring blood glucose level in patients from multi-departments at this hospital.
