Managing diabetes is exhausting. It’s a 24/7 job with no vacations and, honestly, the tools we use shouldn’t make it harder. If you’ve spent any time in the diabetic community, you know that not all hardware is created equal. Contour Next One test strips have basically become the gold standard for people who are tired of getting "ghost" readings that don't match how they actually feel.
Accuracy matters. A lot.
When your meter says 110 mg/dL but you’re actually sitting at 75, that’s a problem. It’s the difference between a normal afternoon and a sweaty, shaky mess on the floor of a grocery store aisle. Ascensia Diabetes Care, the folks behind these strips, leaned heavily into the science of "Multi-Pulse" technology to fix this. It’s not just marketing fluff; it’s about the strip sampling the blood multiple times to filter out the noise.
Why Accuracy Standards Actually Fail You
Most people think their meter is 100% accurate. It isn’t. The FDA and ISO standards (specifically ISO 15197:2013) actually allow for a significant margin of error. For most meters, being within 15% of a lab result is considered "passing."
That’s a huge gap.
If your real blood sugar is 200, a meter could legally show you 170 or 230 and still be "accurate" by industry standards. The Contour Next One test strips are designed to be much tighter than that. In clinical studies, they’ve shown to deliver results within 8.4% of the actual lab reference value. That might seem like a small number, but when you're calculating an insulin bolus for a high-carb meal, that 7% difference is massive. It’s the difference between sticking the landing and ending up in a hypoglycemic tailspin three hours later.

The Second-Chance Sampling Secret
We’ve all been there. You prick your finger, squeeze out a drop, and—oops—it wasn't enough. With most old-school strips, that’s it. Error code. You just wasted a dollar.
The Second-Chance sampling feature on these strips is a genuine lifesaver for your wallet. You get about 60 seconds to apply more blood to the same strip if the first attempt was a dud. This sounds like a minor convenience until you realize how much those little plastic rectangles cost over a year. If you’re testing five times a day and wasting one strip every other day, you’re literally throwing money in the trash.
The Chemistry of FAD-GDH
Let's get nerdy for a second because the chemistry inside the strip is why they work. These strips use FAD-GDH (flavin adenine dinucleotide-glucose dehydrogenase) enzymes.
Why should you care?
Because older strips used glucose oxidase (GOx), which reacts with oxygen. If you’re at a high altitude or using supplemental oxygen, GOx strips can give you wild readings. FAD-GDH doesn't care about oxygen. It also ignores common "interfering substances." If you’ve got high levels of Vitamin C (ascorbic acid) or acetaminophen in your system, some strips will mistake those molecules for glucose. You end up treating a high that doesn't exist. The Contour Next technology is built to ignore those non-glucose signals, giving you a "cleaner" reading.
Coding is Dead (And Good Riddance)
Remember "No-Coding" technology? It feels like ancient history now, but it was a revolution. Every batch of test strips is slightly different due to manufacturing variances. In the old days, you had to manually enter a code from the vial into your meter so it could calibrate. If you forgot, your numbers were garbage. Contour Next One test strips are self-coding. The meter recognizes the strip characteristics automatically. It’s one less thing to screw up when you’re pre-breakfast and haven't had coffee yet.

Real-World Use: Don’t Mess Up the Storage
I see people do this all the time: they leave their strip vial in a hot car or a humid bathroom.
Stop.
These strips are sensitive. The vial has a special desiccant lining to keep moisture out. Every time you pop that lid, you’re letting in ambient humidity. If you leave it open, the enzymes on the strips start to degrade. You won't get an error message; you’ll just get a wrong number.
Keep them between 41°F and 86°F. If you’re hiking in the desert or skiing in Aspen, keep your meter and strips in an internal pocket close to your body heat. Extremes are the enemy of accuracy.
The App Connection and Data Shifting
The "One" in the name refers to the Bluetooth-enabled meter, but the strips are the engine. When you slot a strip into the meter, it triggers the sync to the Contour Diabetes app.
What’s interesting here isn't just the logging; it’s the "SmartLIGHT" feature. The meter glows green, yellow, or red based on the strip reading. It sounds a bit like a toy, but when you’re waking up at 3:00 AM and your eyes are blurry, a red light tells you everything you need to know without having to process the actual numbers.
Why Insurance Companies Play Games
You might find that your insurance suddenly stops covering these strips. It’s not because they aren't good; it’s because of "rebate walls" and "preferred formularies." Insurance companies often strike deals with specific manufacturers. If you’re forced to switch to a generic or a brand you don't trust, talk to your doctor about a "Medical Necessity" waiver. Accuracy isn't a luxury; it’s a requirement for staying alive.
Comparing the Options
There are cheaper strips on the market. You can go to a big-box retailer and get a vial of 50 strips for twenty bucks. Are they okay? Usually. Are they Contour level?

Rarely.
Third-party studies, like those conducted by the Diabetes Technology Society (DTS), have shown that many "store brand" meters fail the accuracy standards that the big players hit consistently. If you’re Type 2 and not on insulin, a 15% or 20% variance might not be a disaster. But if you’re Type 1 or using an insulin pump, you need the precision. The Contour Next One test strips consistently rank at the top of these independent "Blood Glucose Monitoring System Surveillance" reports.
Practical Steps for Better Readings
Getting the most out of your strips isn't just about the technology; it’s about your technique.
- Wash your hands with soap and water. Seriously. Using an alcohol prep pad is okay in a pinch, but it can dry out the skin and sometimes interfere with the sample if it hasn't evaporated. If you just ate an orange and then prick your finger, the sugar residue on your skin will make your reading skyrocket.
- Dry your hands completely. Water dilutes the blood drop. A diluted drop means a lower reading than reality.
- Don't "milk" your finger too hard. If you squeeze too aggressively, you might pull interstitial fluid into the blood sample, which also dilutes the glucose concentration.
- Check the expiration date. It’s not a suggestion. The enzymes lose their potency. Using expired strips is just guessing with extra steps.
The reality of living with a chronic condition is that we are the ones doing the heavy lifting. The tools should just work. Using a high-quality strip like the Contour Next series takes one variable out of a very complicated equation. It gives you a bit of peace of mind in a situation that is often anything but peaceful.
Next Steps for Better Management:
Verify your current meter's accuracy by taking it with you to your next lab draw. Check your blood sugar with your Contour Next One test strips immediately after the phlebotomist draws your blood. Compare your meter's result to the lab's result (usually found in your patient portal as "Plasma Glucose"). If the difference is consistently more than 10%, it’s time to calibrate your technique or check your strip storage conditions. Always ensure your meter's "target ranges" are updated in the app to match the specific goals set by your endocrinologist.
