The FDA’s Class I recall of TRUE METRIX blood glucose meters covers more than the TRUE METRIX name on a store shelf. It includes four TRUE METRIX systems and versions sold under store and distributor names. The FDA has also posted a correction for certain first aid kits that contain TRUE METRIX meters. Here is what the E-5 problem is, which products are covered and what the FDA says to do now.
The E-5 problem
TRUE METRIX meters test a drop of blood on a strip. The recalled meters can show the same message, E-5, for two very different problems. E-5 can mean blood sugar above 600 mg/dL. It can also mean an error with the test strip.
The FDA says a person with very high blood sugar might think the strip failed and delay care. Or a person might treat very high blood sugar when their level is normal or low. The FDA says either mistake could lead to dehydration, confusion, loss of consciousness or death.
The four systems
The FDA lists these Trividia Health systems:
- TRUE METRIX Self-Monitoring Blood Glucose System
- TRUE METRIX AIR Self-Monitoring Blood Glucose System
- TRUE METRIX GO Self-Monitoring Blood Glucose System
- TRUE METRIX PRO Professional Monitoring Blood Glucose System
Store-brand versions
The FDA says the recall also covers cobranded versions sold under store or distribution partner names. These meters may have a pharmacy or store name on the box along with the TRUE METRIX name.
Trividia’s notice lists 20 store and partner names, such as CVS, Walgreens, Kroger and ReliOn (Walmart). The FDA’s full product list includes a few more private-label names. We list them all in our article on store-brand TRUE METRIX meters.
A store name alone does not mean a meter is recalled. Many stores sell other meters that are not part of this recall. Look for the TRUE METRIX, TRUE METRIX AIR, TRUE METRIX GO or TRUE METRIX PRO name on the meter or box. Then compare the item number or UPC with the FDA’s full list, or use the serial number lookup on Trividia’s notice.
Meters inside first aid kits
TRUE METRIX meters can also come inside other products. The FDA posted a correction in June 2026 for two first aid kits made by North American Rescue for emergency medics. The kits contain TRUE METRIX meters. North American Rescue sent a correction letter on March 27, 2026. As of that date, it had reported no serious injuries or deaths linked to the kits.
What the FDA recommends now
The FDA’s safety communication was issued April 28, 2026, and updated May 19, 2026. Its advice has two parts that go together:
- Switch to another way of testing blood sugar, if possible, until corrected meters are available.
- Keep testing. Do not stop using a TRUE METRIX meter until you have another method. Going without testing has its own risks.
The FDA says to talk with a health care provider or pharmacist about switching. If you see E-5 and have symptoms of high or low blood sugar, the FDA says to contact your health care provider right away.
Reported injuries
The FDA says that as of January 16, 2026, Trividia had reported 114 serious injuries and one death associated with this issue. These are reports, not findings that the meter caused each event. The numbers may have changed since that date.
A meter, not a CGM
TRUE METRIX meters are blood glucose meters. They are not continuous glucose monitors, and this recall is separate from recent notices about FreeStyle Libre sensors and Dexcom receivers and apps.
