There is documented risk for transmission of Healthcare Associated Infections, most notably HIV and Hepatitis B Virus, with glucometers and also lancing devices. According to the US Centers for Disease Control and Prevention Guidelines for Disinfection and Sterilization, glucometers should be thoroughly cleaned and disinfected between patient-use with an EPA-registered disinfectant with relevant claims against bloodborne pathogens (HIV and Hepatitis B Virus). If there is blood or other organic matter present, cleaning should precede the disinfection process. The use of a low-level or intermediate-level EPA-registered disinfectant is required between patient-use. If a patient uses their own meter, it is still recommended that cleaning and disinfection take place between use to prevent potential contamination. Additionally, the use of a reusable lancing device is not recommended for healthcare settings.
