Accu-Chek field safety notices

Patient safety is our first priority. We are committed to keeping those who use our products, as well as healthcare professionals, informed of issues and solutions related to our products and services.

Specific lots of Accu-Chek Performa test strips potentially showing an increased number of strip errors prior to dosing or biased results

At Roche Diabetes Care we hold our products to the highest standards of quality and are committed to communicating any issues impacting the operation of our products. This is why we would like to inform today about an issue that might occur in certain lots of the Accu-Chek Performa test strips. As part of our ongoing quality monitoring and market surveillance processes, we have identified certain test strip lots that potentially show an increase in strip errors prior to dosing. 

Due to the designed fail-safe in the blood glucose meter, the issue can be identified by an error message displayed on the meter upon strip insertion or through the device not recognising the test strip. However, in a very limited number of cases the test strip can produce a biased result i.e. a falsely too high or too low value, which you might not be able to detect easily and which could lead to erroneous therapy adaptations.

What to do next

Check the lot numbers of your test strip supply against the complete list. You can find the lot number on the top flap of the vial packaging as well as on the label of each test strip vial.

Discontinue using strips from the affected lots immediately and please return to the pharmacy or store where you obtained the strips for a replacement pack. If your test strip supply is not from the lots affected, you can continue using these test strips and no additional action is required.
