McCune Law Group Investigating True Metrix Blood Glucose Monitor Injuries

ONTARIO, Calif., May 28, 2026 — McCune Law Group has launched an investigation into injuries and deaths linked to True Metrix blood glucose monitoring systems manufactured by Trividia Health, Inc., following an April 28, 2026, FDA Class I Recall connected to at least 114 reported injuries and one reported death. 

Video Transcript 

“So the FDA issued a Class I recall — their most serious — on the True Metrix blood glucose monitors. And the issue is something that I think is really important for people to understand. 

There’s an error code on these devices — E-5 — and it can mean one of two things. It could be a bad test strip, which is essentially a non-issue. Or it could mean your blood sugar is critically high. The problem is the device doesn’t tell you which one it is. For someone managing diabetes, that’s a really dangerous gap. 

The other thing I want people to know is that this goes beyond meters that say TRUE METRIX on the box. Trividia manufactures these devices under store-brand names — CVS, Walgreens, ReliOn at Walmart, Kroger, Publix, among others. So if you bought a blood glucose meter at a pharmacy and TRUE METRIX appears anywhere on the device or the test strip packaging, it’s affected by this recall. 

114 injuries and a death have been reported. We think that number is likely higher, because these types of harms often don’t get connected back to the device. 

I’m Kristy Arevalo, I’m an attorney at McCune Law Group. We’re investigating cases on behalf of people who were seriously injured while using these devices — if that includes you or someone in your family, we’d like to talk.” 

What the FDA Found 

True Metrix, True Metrix Air, True Metrix Go, and True Metrix Pro devices display an “E-5” error code in two distinct situations: when a user is experiencing a dangerously high blood glucose event exceeding 600 mg/dL, and when a test strip has simply malfunctioned. The device’s original instruction booklet did not tell patients which situation they were facing, leaving them unable to determine whether they were in a medical emergency. 

The FDA first issued an Early Alert in February 2026. Three months and three escalations later, it upgraded the matter to a full Class I recall and advised all True Metrix users to switch to an alternative testing method immediately. Walmart issued its own separate recall on May 5, 2026. 

Millions May Not Know They Are Affected 

The recall extends well beyond the True Metrix brand name. Trividia Health distributes its devices under more than 20 store brand names, including Walmart (ReliOn), CVS, Walgreens, Rite Aid, Kroger, Publix, H-E-B, and Albertsons. Most patients who purchased store-branded meters have no way of knowing their device is a Trividia product subject to this recall. The meter itself will display True Metrix even when the box does not. 

“For individuals managing diabetes, a glucose monitor is not just a convenience. It is a lifeline,” said Kristy M. Arevalo, partner at McCune Law Group and lead attorney on the matter. “We believe the number of people harmed is far greater than what has been reported, particularly among patients who purchased these devices under store brand names.” 

Who May Have a Claim 

McCune Law Group is investigating cases involving California residents who used a True Metrix device or store-branded equivalent on or after February 2026, received an E-5 error code, and suffered serious harm including hospitalization, diabetic ketoacidosis, loss of consciousness, organ damage, or death. A photo of the device, a receipt, or documentation of an E-5 error may be sufficient to open a case.
