Home use and Point of Care blood glucose monitoring system: Accu-Chek Aviva, Accu-Chek Performa and Accu-Chek Inform II test strips – risk of strip error messages and false high and low blood glucose results

Affected test strips, manufactured by Roche Diabetes Care, may give increased strip error messages prior to dosing with blood and in some cases may give false high or low readings, which may be hard to detect.


Healthcare personnel who manage patients using these devices:

  • Identify patients who use Accu-Chek Aviva, Accu-Chek Aviva Nano, Accu-Chek Aviva Expert, Accu-Chek Aviva Combo, Accu-Chek Aviva Insight, Accu-Chek Performa Nano meters.
  • Advise patients to discontinue use of Accu-Chek Aviva and Accu-Chek Performa blood glucose test strips with affected lot numbers, see FSN.
  • Return affected test strips to the pharmacy where they were dispensed or purchased from for replacements.
  • Ensure that patients are aware of this information and that they have an alternative testing means, if required.
  • Ensure the patient can continue to monitor their blood glucose effectively.
  • If patients are concerned about their blood glucose readings when using this meter, advise them to contact their healthcare professional.

Healthcare personnel who use Accu-Chek Inform II test strips with Accu-Chek Inform II and Accu-Chek Performa meters:

MHRA understands that Accu-Chek Inform II test strips have only been supplied by Roche for professional use in the UK.

  • Ensure all relevant members of staff receive the FSN and can continue to monitor patient’s blood glucose effectively, using an alternative means if required.
  • Dispose of any affected lots.
