Technical accuracy of ten self-monitoring blood glucose devices commonly used in Dhaka City of Bangladesh

TECHNICAL ACCURACY OF TEN SELF-MONITORING BLOOD GLUCOSE DEVICES COMMONLY USED IN DHAKA CITY OF BANGLADESHtBackgroundIntroduction of Self-Monitoring Blood Glucose (SMBG) Devices is a landmark in the history of diabetes management and prevention; however, the potential of this revolution may not be realized if the technical accuracy of the devices is not ensured. Due to unregulated nature of the marketing in many countries, consumers are victims of unethical promotion of SMBG systems. Evidence are thus required on the technical accuracy of these Devices which can help the Policy Makers and Implementing Executives to protect and guide the public to choose devices with acceptable quality within a reasonable price range.Aimto evaluate the technical accuracy of ten most commonly used SMBG Devices marketed in Dhaka City of Bangladesh.MethodUnder an experimental study design 10 SMBG Devices commonly sold in Dhaka City, selected though a Retailer-based survey, were subject to the accuracy test. One hundred type 2 diabetes mellitus (T2DM) subjects (aged 30-60 yrs) were recruited from the BIHS Hospital (a tertiary care hospital). Female subjects with pregnancy or lactation were excluded and also any subject with an acute or chronic complication of DM or any other clinically evident major disorders were excluded. After standard preparation the experiments were performed in the morning. Blood glucose measurement by SMBG Devices was done following the enclosed instruction of the specific Devices. The Laboratory measurement of blood glucose was done by enzymatic method using the Dimension RXL automated chemistry analyzer and average results from duplicate measurements were taken and expressed in a blinded manner. Hematocrit was measured using Sysmex XT 2000 hematology autoanalyzer. Data were analyzed by paired t-test and Pearsonu2019s correlation analysis.ResultsThe results of all devices generated from the two equipment differed from each other significantly (p
