I understand you're asking about the expiry date of Accu-Chek Performa Test Strips, 100 Count. However, the specific expiry date is not provided in the available product information. Typically, the expiry date is printed on the packaging of the test strips themselves.

For accurate and safe use, please check the box or container of your test strips for the expiry date. If you cannot find it or have concerns about the product's validity, I recommend consulting a pharmacist or a diabetes specialist doctor for guidance.

If you need further assistance with blood glucose monitoring or related supplies, please feel free to ask.
