OBJECTIVES: To investigate the cause of a persistent test strip error code, error 2b, appearing on LifeScan SureStep Flexx glucose meters (Johnson and Johnson, Rochester, USA). DESIGN AND METHODS: SaniCloth Plus (The Dynarex Corporation, Orangeburg, USA), CaviWipes XL (Metrex, Orange, USA), and Accel (HANSA Med Ltd., Mississauga, Canada) sanitizing agents were tested in an attempt to reproduce the error. RESULTS: The error 2b code was encountered when the Accel was used as a cleaning agent, but not when SaniCloth Plus or CaviWipes XL were used. CONCLUSIONS: The hydrogen peroxide contained in Accel (HANSAmed, Ltd., Mississauga, Canada) interferes with the glucose oxidase reaction on the test strip, causing the error 2b code.
