The FDA warns TRUE METRIX meters can show one E-5 code for two very different problems. Don't stop testing — but arrange a backup meter when you can.
A safety alert for anyone using a TRUE METRIX blood glucose meter. The FDA has flagged a serious problem — the same "E-5" error code can mean either dangerously high glucose OR a simple test strip error. Those need opposite responses, and getting it wrong can be dangerous. We explain what the FDA is recommending and, importantly, what NOT to do.
In this episode:
• Which meters are affected — TRUE METRIX, AIR, GO, PRO, and cobranded versions
• Why one error code for two situations is a real safety risk
• The FDA's most important instruction — don't stop testing abruptly
• Who's at highest risk — people on intensive insulin or sulfonylureas
• How to switch to a backup testing method safely
• What to do if you see an E-5 error with symptoms
Key takeaway: If you use TRUE METRIX, arrange another testing method when you can — but keep monitoring until your backup is ready. If an E-5 error appears and you feel symptoms of high or low glucose, get help rather than guessing.
