Why Monitoring Matters More Than Ever
Diabetes affects more than 38 million Americans, and millions more live with prediabetes without knowing it. The daily reality for many people is a familiar ritual: prick the finger, squeeze a drop of blood onto a strip, wait five seconds, and jot down the number. Traditional blood glucose monitors have served this purpose well for decades, and they remain the most affordable entry point for most households.
But the conversation has shifted. In March 2024, the FDA cleared the first over-the-counter continuous glucose monitor, and the market opened up in a way that changed who can access real-time glucose data. You no longer need a diabetes diagnosis or a prescription to see how your body responds to food, exercise, and sleep. That single change has made blood sugar monitoring relevant to a much wider audience than ever before.
The Two Main Paths: Traditional Meters and CGM
Traditional Blood Glucose Meters
The classic fingerstick meter is still the workhorse of diabetes care in the US. These devices are inexpensive, require no prescription, and give you an instant reading of your blood sugar at that exact moment. They are especially useful for people who only need to check a few times a day, or who want a backup method to verify a CGM reading.
What you pay for a traditional meter depends largely on the strips. The meter itself is often surprisingly affordable, but strips are where the ongoing cost lives. A typical starter kit that includes a meter, test strips, lancets, and a lancing device can run somewhere between $20 and $40. Test strips for a month of regular use typically cost between $15 and $50 depending on the brand and how often you test.
Some pharmacies and retailers offer store-brand strips that work with their own meters at noticeably lower prices. For people who test several times a day, those savings add up quickly. The trade-off is that you only see a snapshot of your glucose at the moment you test, and you will miss patterns that happen between checks, especially overnight.
Continuous Glucose Monitors
A CGM does something a traditional meter cannot. It measures your glucose from the interstitial fluid just below the skin every few minutes, around the clock, and sends that data to an app on your phone. You can see trends, catch overnight lows, and understand exactly how a meal affects your levels for hours afterward.
The CGM market in the US now splits into two categories. Prescription CGMs like the Dexcom G7 and the FreeStyle Libre 3 Plus are designed for people with diabetes, often with alarms for dangerously high or low readings, and they integrate with insulin pumps for some users. Over-the-counter CGMs like Dexcom's Stelo and Abbott's Lingo are marketed for adults who want metabolic insight without a diabetes diagnosis.
The cost difference is significant. A prescription CGM without insurance can run several hundred dollars for a month of sensors. A Dexcom G7 receiver costs around $377, and a 30-day supply of sensors runs roughly $489 at average retail prices. Most insurance plans and Medicare cover these devices for people who qualify, which brings the out-of-pocket cost down considerably for those with coverage.
The OTC options are more approachable. Stelo sells a two-sensor pack for about $99, giving you up to 30 days of wear time, with a subscription option that brings the monthly cost down further. Lingo launched at Walmart at just under $50 for a two-week pack, making it the first CGM available on store shelves at a major US retailer. Both work with iOS and Android apps, and both require no prescription.
How to Choose What Is Right for You
The right choice depends on your situation, and there is no single answer that fits everyone. Here is a practical breakdown of what different types of people tend to need.
If you have type 1 diabetes or type 2 diabetes requiring insulin, a prescription CGM is usually the strongest option. The alarms, the integration with insulin pumps, and the ability to share data with your care team make a meaningful difference in daily safety. Many endocrinologists in the US now recommend CGM as the standard of care for insulin users, and insurance coverage is widely available.
If you have type 2 diabetes managed with oral medication and lifestyle changes, you have more flexibility. Some people do perfectly well with a traditional meter checked a few times a day. Others find that a CGM helps them understand which foods spike their glucose and keeps them motivated. The OTC options make this affordable to try without a prescription.
If you are simply curious about your metabolic health, athletic performance, or how your body processes different foods, the OTC models are worth a look. A two-week starter pack lets you test the experience without a large commitment. Many users report that seeing real-time glucose responses to meals changes their eating habits in ways that lab results never did.

Saving Money Without Sacrificing Accuracy
Cost is the biggest barrier for many Americans, especially those without insurance or with high-deductible plans. There are several practical ways to reduce what you spend.
For traditional meters, the biggest lever is strip choice. Store-brand strips that pair with their own meters often cost a fraction of national brand names. Buying strips in larger quantities also lowers the per-strip price. Some pharmacy chains run regular promotions on glucose testing supplies, and manufacturer coupons for branded meters and strips appear frequently.
For CGMs, the picture is more nuanced. If you have diabetes and qualify, insurance coverage through a prescription is almost always the cheapest route, even with a copay. Medicare covers CGM for beneficiaries with diabetes who meet certain criteria, and this coverage expanded in recent years. For people without coverage, manufacturer patient assistance programs and pharmacy discount cards can bring the price down significantly. The OTC options bypass insurance entirely, and subscriptions reduce the monthly cost versus buying single packs.
Another consideration is HSA and FSA accounts. Many Americans pay for glucose monitors, sensors, and strips with pre-tax health savings dollars, which effectively reduces the cost. Both Stelo and Lingo can be purchased with HSA or FSA funds, and most traditional meters and strips qualify as well.
A Real-World Look at Getting Started
Let us walk through what the first week looks like for someone starting with an OTC CGM, since that is the newest and most common path for people without a diabetes diagnosis.
Day one, you order a starter pack online or pick one up at a local retailer. The package includes the sensor and access to the companion app. You download the app, create an account, and attach the sensor to the back of your upper arm. The insertion feels like a quick pinch, similar to a fingerstick, and most people report they forget it is there within a few hours.
Over the next two weeks, the app builds a picture of your glucose patterns. You will see how a bagel at breakfast moves your numbers differently than eggs, how a walk after dinner flattens a spike, and how sleep quality shows up in your morning readings. This is the part that converts skeptics. Seeing your own data, in real time, is far more persuasive than reading a generic nutrition handout.
At the end of the sensor's life, you remove it and apply a new one if you are continuing. The app keeps your history, so you can look back at months of trends. Some users pair the data with a traditional meter to confirm readings occasionally, which remains a good habit, especially in the first week when you are learning how the CGM responds to rapid changes.
Local Resources and Where to Find Help
Where you live in the US can shape both your options and your costs. Major pharmacy chains like CVS, Walgreens, and Walmart carry meters, strips, and now OTC CGMs in many locations. Walmart's rollout of the Lingo system put CGMs on store shelves for the first time, and other retailers are expected to follow.
Many communities have diabetes education programs run through local hospitals, community health centers, or organizations like the American Diabetes Association. These programs often provide free or low-cost education sessions, and some connect participants with discounted testing supplies. Endocrinologists and primary care doctors remain the best first stop for anyone with a diabetes diagnosis, because they can write the prescription that unlocks insurance coverage for CGM.
For those without a regular doctor, telehealth services now offer a convenient alternative. Several platforms connect you with a clinician who can evaluate whether a prescription CGM is appropriate, and the entire process can happen without an in-person visit. This has become a common route for people who want the alarm features of a prescription device but have trouble getting an appointment.
The Bottom Line on Blood Sugar Monitoring
The era of choosing between a basic fingerstick meter and nothing else is over. Americans today have an unusually wide range of options, from $35 starter kits to subscription CGMs that stream glucose data to your phone every few minutes. The best choice depends on your health status, your budget, and what you hope to learn from the data.
For people managing diabetes, especially those on insulin, a prescription CGM with insurance coverage remains the most powerful tool available. For everyone else, the OTC options from Stelo and Lingo have made real-time glucose monitoring accessible in a way that was unimaginable just a few years ago. A traditional meter still has an important place, both as a low-cost daily tool and as a way to verify CGM accuracy.
Start with your own situation. If you have diabetes, talk to your doctor about whether CGM makes sense and what your insurance covers. If you are curious about your metabolic health, a two-week starter pack is a low-risk way to find out what the data can tell you. Either way, the important thing is to begin. The numbers have a lot to say, and knowing them beats guessing every time.
