Stelo eligibility depends on the exact model and its current label. As of October 14, 2026, the FDA’s June 12, 2026 clearance describes Stelo for people age 2 and older who do not use insulin, while a current Stelo subscription listing still says it is for people age 18 and older. Before you spend money, match the model you are considering to its current Instructions for Use and ask the seller which label applies to that order.
A continuous glucose monitor can show patterns between appointments, but it does not replace the blood tests used to diagnose prediabetes or diabetes. The NIDDK explains insulin resistance and prediabetes, including the blood tests a primary-care professional may use.
What does the current FDA clearance say about Stelo?
The FDA announcement dated June 12, 2026 describes an over-the-counter Stelo glucose biosensor cleared for people age 2 and older who are not using insulin. That is the current FDA statement to start with when you are checking eligibility.
The age difference matters because a current subscription listing gives a different commercial description: it says Stelo is for people age 18 and older who are not using insulin. That listing also says not to use it with problematic hypoglycemia or dialysis. Treat those as model- and label-specific purchase details, not a blanket rule for every CGM.
Use this exact eligibility checklist
- Write down the full product name: Stelo Glucose Biosensor System, not simply “a Dexcom monitor.”
- Ask whether the item uses the FDA-cleared label that includes ages 2 and older, or a label that says ages 18 and older.
- Confirm whether you use insulin.
- If you have problematic hypoglycemia, ask whether this specific model is appropriate before ordering.
- Confirm that your phone meets the app’s compatibility requirements.
You can bring that list to a visit alongside a short symptom timeline if you are trying to make sense of glucose patterns or low-glucose symptoms.
How do insulin use and low blood sugar affect suitability?
The current FDA clearance described above is for people who do not use insulin. Medicare uses a different rule for coverage: Medicare says it may cover a CGM for someone with diabetes who takes insulin or has a history of hypoglycemia, when a health care provider orders it and the other requirements are met. Device eligibility and insurance coverage are separate questions.
The NIDDK says low blood glucose is more likely in people who use insulin or certain other diabetes medicines, and that some CGMs can sound an alarm when glucose falls below a target range. Do not assume Stelo has that feature: one current retailer listing describes Stelo as alert-free. The exact model’s label is the place to confirm alerts, readings, and what to do when a number does not match how you feel.
Script for your visit: “I am considering the Stelo Glucose Biosensor System. I do or do not use insulin, and I have or have not had low blood sugar. Does its current label fit my situation, and what should I use to confirm a reading that does not match my symptoms?”
How often does Stelo check glucose?
Continuous glucose monitoring estimates glucose throughout the day and night. The NIDDK CGM guide says CGMs generally estimate glucose every few minutes from fluid between cells and may require comparison with a finger-stick meter in some safety situations. For Stelo specifically, Levels says Apple Watch readings from the Stelo app update about every 15 minutes. That is an app-display detail, not a reason to assume every Stelo model has the same features.
What will Stelo cost?
Prices below were shown on October 14, 2026; check the checkout for today’s price. These listings describe different sellers and terms, so they are not interchangeable.
| Listing | Shown price | What the listing says |
|---|---|---|
| Stelo subscription | $89.00 per month | Monthly auto-renewal; one box includes two sensors for up to 30 days of wear; all sales final, with no returns or exchanges. |
| NES Shop listing | $99.00 USD | Shown as sold out when captured; describes two biosensors with up to 30 days of total wear. |
| Medicare-covered CGM | Varies | After the Part B deductible, Medicare says you pay 20% of the Medicare-approved amount when the supplier accepts assignment. |
Neither listing answers whether Stelo is the cheapest CGM without insurance, whether Costco or Walmart has it, or whether there is a free trial. Ask the store or seller for current stock, return terms, and the total cost before checkout. If you are comparing a prescription CGM such as FreeStyle Libre 2, ask your prescriber and pharmacy what that model requires and what your plan covers.
Is Stelo worth the money for you?
That comes down to what you need it to answer. The seller describes Stelo as a way to see how food, activity, and sleep relate to glucose patterns. A CGM may give you trend information over hours and days; an A1C test answers a different question, because the NIDDK says an A1C reflects average glucose over about three months.
If your goal is a clear primary-care conversation, save the questions that matter most: whether the label fits your age and insulin use, what alerts it has, what it costs over the time you plan to use it, and whether your insurance has a covered alternative. For help organizing medication questions, use this prescription-question guide.
Before you order
- Ask the seller for the exact current Stelo label and age indication.
- Confirm whether you use insulin and whether you have problematic hypoglycemia.
- Check your phone and operating-system compatibility.
- Ask for the full recurring cost, cancellation steps, and return terms.
- If you want Medicare coverage, ask your health care provider and supplier whether you meet Medicare’s requirements.
Your next step: write down your age, insulin use, low-blood-sugar history, phone model, and coverage question, then use the script above to check exact Stelo eligibility before you order.
