True Metrix Blood Glucose Monitor Recall
The medical device attorneys at McCune Law Group are investigating serious injuries and deaths linked to defective True Metrix blood glucose monitoring systems manufactured by Trividia Health. In April 2026, the FDA issued a Class I recall — its most serious classification — after discovering that a software design flaw causes the device’s E-5 error code to appear both during a life-threatening high blood glucose event and during an ordinary test strip error, with no way for patients to tell the difference. At least 114 serious injuries and one death have been reported to the FDA. If you or a loved one was hospitalized or suffered serious complications after receiving an E-5 error code on a True Metrix device — or a store-branded equivalent sold at Walmart, CVS, Walgreens, or another major pharmacy — you may be entitled to compensation.

Experienced Medical Device Attorneys Fighting for Diabetics
McCune Law Group is accepting cases from individuals who have suffered harm due to defective True Metrix, True Metrix Air, True Metrix Go, and True Metrix Pro blood glucose monitoring systems made by Trividia Health. For nearly two decades, our firm has held medical device manufacturers accountable when their products put patients at risk.
We bring deep experience in pharmaceutical litigation, product liability, and medical malpractice, and we understand that when you’re managing diabetes, you trust your life to these devices. When they fail, the consequences can be devastating.
A Software Flaw Left Patients No Way to Know If They Were in Danger
Trividia Health has acknowledged a software design defect affecting True Metrix blood glucose monitoring systems. The defect causes the device’s E-5 error code to appear in two entirely different situations, with no way for the patient to distinguish between them:
- A test strip error — meaning the reading is invalid and blood glucose may be normal
- A dangerously high blood glucose event — a medical emergency requiring immediate treatment
For people managing diabetes, who make life-or-death treatment decisions based on their meter readings, that ambiguity is not a minor inconvenience. It is a safety failure.
The instruction booklet that shipped with these devices did not tell patients to seek medical attention when they saw the E-5 code until February 2026. By then, patients may have been living with this defect for years.
How the Recall Escalated
- February 2026: Trividia Health issued a labeling correction; the FDA issued an Early Alert.
- April 28, 2026: The FDA upgraded to a Class I recall — its most serious classification, reserved for devices that could cause serious injury or death. The FDA also issued a full Safety Communication advising all True Metrix users to switch to an alternative testing method as soon as possible.
- May 5, 2026: Walmart issued its own separate recall for True Metrix devices sold at its locations.
By the Numbers
As of May 2026, there have been:
- At least 114 serious injuries reported to the FDA
- 1 death linked to the E-5 error code defect
- 20+ store brand names affected, sold at major pharmacies nationwide
The FDA has warned that the ambiguous error code can lead to incorrect treatment decisions with potentially fatal consequences. If you relied on a True Metrix device for your diabetes management, you need to know your rights.
Serious Health Risks from the E-5 Error Code
When you have diabetes, accurate glucose monitoring isn’t just important; it’s essential to your survival. An ambiguous error code on a defective glucose monitor can trigger a cascade of serious health complications.
If a Patient Assumed E-5 Was a Test Strip Error (and Did Nothing)
- Severe hyperglycemia (dangerously high blood sugar)
- Diabetic ketoacidosis (DKA)
- Excessive thirst and frequent urination
- Rapid heartbeat and hyperventilation
- Nausea and vomiting
- Confusion and altered mental state
- Loss of consciousness
- Death
If a Patient Assumed E-5 Indicated High Glucose (and Over-Treated)
- Severe hypoglycemia (dangerously low blood sugar)
- Confusion, dizziness, and disorientation
- Tremors and excessive sweating
- Seizures
- Loss of consciousness or coma
- Brain damage from prolonged low blood sugar
- Death
Did You Buy Your Meter at Walmart, CVS, Walgreens, or Another Major Pharmacy?
Trividia Health distributes its devices under more than 20 store brand names across the country. If you purchased a blood glucose meter at any of the following retailers, the device inside may be a True Metrix system covered by this recall, even if the box doesn’t say True Metrix:
- Walmart (ReliOn)
- CVS
- Walgreens
- Rite Aid
- Kroger
- Publix
- Meijer
- H-E-B
- Hy-Vee
- Albertsons (Signature Care)
- Humana / CenterWell
- And others
Check the meter itself — not just the box. Even if the front label shows a store brand name, the meter will display TRUE METRIX if it is part of this recall.
Do You Qualify? Review These Requirements
You may be eligible for compensation if:
- ✓ You used a True Metrix, True Metrix Air, True Metrix Go, True Metrix Pro, or store-branded equivalent on or after February 2026
- ✓ You received an E-5 error code from your device
- ✓ You were subsequently hospitalized, or suffered serious complications including severe hyperglycemia, hypoglycemia, diabetic ketoacidosis (DKA), loss of consciousness, organ damage, or death
You do not need to have the original box or lot number to contact us. A photo of the device, a receipt, or documentation of an E-5 error resulting in an abnormal reading may be sufficient to open a case.
If a loved one died after receiving an E-5 error code on a True Metrix or store-branded device, surviving family members may have the right to pursue a wrongful death claim.
If you’ve experienced any of these effects while using a True Metrix or store-branded equivalent, call or contact McCune Law Group for a free case review today.
Follow These Steps to Protect Your Rights
- Identify your device — check whether your meter displays True Metrix, even if the box shows a store brand name.
- Preserve the meter, test strips, and packaging — do not throw anything away.
- Take photographs of the meter face, serial number, and all packaging.
- Document everything — dates of use, symptoms experienced, and medical treatment received.
- Save all medical records related to hospitalizations, emergency room visits, or doctor appointments connected to a glucose-related event.
- Note any communications with Trividia customer service or healthcare providers about the E-5 error code.

Frequently Asked Questions
My meter says ReliOn, CVS, or another store name. How do I know if it’s part of this recall?
Check the meter itself, not the box. Trividia Health manufactures blood glucose meters sold under more than 20 store brand names at pharmacies and retailers across the country. Even if the packaging shows a store name, the meter face will display True Metrix if it is one of the affected devices. If your meter says True Metrix, True Metrix Air, True Metrix Go, or True Metrix Pro anywhere on it, it may be covered by this recall. If you’re still not sure, call us. We can help you figure it out at no cost.
I got an E-5 error code, but I’m not sure what I did next. Do I still qualify?
Possibly, yes. The recall centers on Trividia’s failure to warn patients that E-5 could signal a life-threatening glucose emergency. Whether you retested with a new strip and waited, sought immediate care, or administered insulin based on what you saw, what matters most is whether you experienced a serious health consequence afterward. Call us and we’ll help you assess your situation.
What injuries qualify for a case?
McCune Law Group is currently investigating cases involving hospitalization and other serious health consequences connected to an E-5 error code event. These include: severe hyperglycemia, hypoglycemia, diabetic ketoacidosis (DKA), loss of consciousness, and organ damage. If you are unsure whether your experience meets the threshold, the consultation is free and confidential.
I don’t have the box or lot number anymore. Can I still pursue a claim?
Yes. You do not need the original packaging to contact us. A photo of the meter, a receipt, or any documentation of an E-5 error resulting in an abnormal glucose reading may be sufficient. If you’re unsure what you have, call us anyway. We’ll help determine what documentation may still be available.
How long do I have to file a claim?
In California, personal injury and product liability claims must generally be filed within two years of the date of injury. Do not wait to find out where you stand. Contact McCune Law Group as soon as possible for a free evaluation of your claim and timeline.
Will I have to go to court?
Many product liability cases are resolved through settlement negotiations without going to trial. However, if Trividia Health is unwilling to offer fair compensation, we are fully prepared to litigate. We’ll keep you informed at every stage and discuss all your options along the way.
