The error code description and recommended actions for the E-5 error code in the labeling do not: (a) clearly emphasize that an E-5 error code could represent a very high blood glucose level, and (b) prominently convey the appropriate immediate actions, such as contacting a healthcare professional. This could lead to a delay in treatment if the user does not seek medical attention immediately when receiving an E-5 error code and experiencing symptoms of high glucose. - **Classification**: Class I - **Recalling firm**: Trividia Health, Inc. - **Quantity**: 1,407,465 - **Agency-reported status**: Ongoing - **Source record identifier**: Z-1548-2026 [Open the official record](https://api.fda.gov/device/enforcement.json?search=recall_number%3A%22Z-1548-2026%22) [What the recall classes mean](https://isitonrecall.com/guides/recall-classes/).
