Quality Control of Self-Monitoring of Blood Glucose: Why and How?

Abstract

The control of analytical quality of self-monitoring of blood glucose (SMBG) is recommended as a routine procedure in diabetes management. This control procedure should be easily accessible to patients, convenient, not time-consuming, and provide a reliable assessment of glucose meter performance. Optimally it should be located in the diabetes outpatient clinic. Presently there are two approaches to carrying out SMBG quality control. The first is based on the comparison of results obtained by a controlled glucose meter and use of the laboratory method or point-of-care testing device as a surrogate reference analyzer. The second one is a traditionally organized external quality assessment scheme with use of a dedicated control material, which is distributed to all participants. The recommended allowable meter error in SMBG can be realistically set at 10%.

Evaluation of the Analytical Performance of the Coulometry-Based Optium Omega Blood Glucose Meter

“…However, this kind of analytical variability should be detected when the analytical quality control of glucose meters is carried out properly. 15 In comparison to the laboratory method across the whole range of glucose concentrations measured, the Optium Omega glucose meter yielded mean error amounting to 2.48% ( Table 2), thus remaining below the limit of allowable error equal to 5% recommended by the ADA. 3 The accuracy of measurements using the evaluated glucose meter was equal to that required in DIN EN ISO 15197.…”

“…Third, errors from transient loss of sensitivity, and random noise confound CGM data ( 62 – 64 ). Thus, filtering, denoising, and artifact rejection in CGM data are important for closed-loop control.…”
