Disinfectant wipes containing hydrogen peroxide induce overestimation of glucose results obtained with Lifescan SureStep Flexx® glucose meter.
OBJECTIVE
Investigate the interference of Virox® disinfectant wipes containing hydrogen peroxide with Lifescan SureStep Flexx® glucose meter results.


METHODS
Glucose measurements of control and whole blood samples were performed before and after cleaning with Virox® wipes to reveal the kinetics of this interference.


CONCLUSIONS
After a period where the error code 2(b) is given by the device, an overestimation period of glucose results is always present at all levels tested for a duration of hours. As this interference cannot be detected by the operator, hydrogen peroxide containing wipes for sanitizing of the glucose oxidase based glucose meter must be forbidden.
