FDA warns TRUE METRIX users to switch glucose meters if possible after Class I recall tied to E-5 error code confusion
The FDA says some TRUE METRIX blood glucose meters can show the same E-5 code for two different problems: a very high blood sugar reading or a test strip error. That confusion can delay treatment or lead to the wrong response. The agency says people should move to an alternative testing method if possible, but keep testing until a backup is ready.
