Best Blood Glucose Test Strips of 2026: How to Choose
We buy sealed diabetic supplies for cash. We do not sell supplies.
The best blood glucose test strips are the ones made for your meter, bought new and sealed, stored the right way and used before they expire. Strips only work with the meter they were built for. So picking strips really means picking a meter system your doctor and your plan support.

This page is general information, not medical or legal advice. Talk to your doctor or pharmacist about your own care.
Here's how to judge accuracy, what to check on the box, and the mistakes to avoid. We buy sealed strips, but we don't sell strips or meters, so we have no brand to push.
What accuracy should you expect?
The FDA sets a bar for meters sold over the counter. Its 2020 guidance calls for 95% of results to fall within 15% of a lab value, and 99% within 20%.
What does that mean in real life? Say your true blood sugar is 100. Most readings should land between 85 and 115. Almost all should land between 80 and 120.
That's why two readings a few minutes apart can differ a little. Small gaps are normal. Big, repeated gaps are worth a call to your doctor or the maker.
Strips aren't the only factor. The meter, the strip and how you test all work together. Clean, dry hands help. So does a full drop of blood, put on the strip the way your meter's guide shows.
How to choose blood glucose test strips
Start with these five checks:
- Match the meter. The strip box names the meter it works with. A different strip won't give you a correct reading.
- Ask your plan. Many plans cover only certain brands. Your pharmacist can tell you which ones, often in a minute.
- Check the date. Look for the hourglass symbol on the box and vial. Don't buy or use strips past that date.
- Check the seal. The FDA says to buy new, unopened vials and not pre-owned strips.
- Buy from a trusted source. The FDA says to buy from a local pharmacy or the strip maker.
If cost is a problem, say so. The FDA says some makers offer patient assistance programs, coupons or prescription cards. Your doctor or pharmacist can help you find one.
Why skip pre-owned strips?
The FDA warns against buying pre-owned test strips for a few reasons. You can't know if they were stored properly. They could be expired, or the dates could have been changed or covered up.
Vials opened by someone else may carry small amounts of blood, which raises infection risk. And strips not cleared for U.S. sale may give wrong results. The FDA says to always use new strips authorized for sale in the United States.
Wrong results aren't a small thing. The FDA notes they can lead you to take too much or too little medicine.
Does Medicare cover test strips?
Yes, in many cases. Medicare Part B covers blood sugar test strips as diabetic supplies. After you meet the Part B deductible, you pay 20% of the Medicare-approved amount.
Private plans vary. Call the number on your card and ask which brands are covered and how many strips you can get.
One more note if you're on Medicare or Medi-Cal. Supplies paid for by those programs shouldn't be resold. We don't buy them. If your plan sends more than you use, ask your supplier to lower the amount instead.
How should you store strips?
Moisture, heat and air can affect strips. The FDA says strips must be stored properly to give accurate results.
Simple habits help:
- Keep strips in their original vial.
- Close the cap right after you take one out.
- Store them indoors, away from the bathroom and the stove.
- Never leave them in a hot car.
- Follow the temperature range printed on the box.
Your box or insert lists the exact range for your brand. Check it once, then pick a spot at home that stays inside it.
Write the date you open each vial on the label. Some brands say to use a vial within a set time after opening. Your insert will tell you if yours does.
A real-life example
Say your plan changes, and your doctor moves you to a new meter. You still have six boxes of strips for the old one. They won't work with the new meter.
Don't open them or toss them. Check that each box is sealed and in date, and set them on a cool shelf. Sealed, in-date boxes like these can still help someone who uses that meter.
Then make a short list. Write the brand, the count per box and the date for each one. That list is all you need to ask your pharmacist a question, or to ask a buyer for a quote.
If you're in the same spot, don't wait. Strips lose value as the date gets closer. Our page on how much test strips are worth explains why.
Do CGM users still need strips?
Often, yes, as a backup. Many people with a CGM keep a meter for times when readings don't match how they feel. Ask your doctor how many strips you need.
Strips for a backup meter can sit for months. Check the date on that box every so often, so you aren't stuck with an expired vial when you need it.
If you're comparing sensors too, our CGM comparison lays out the main options side by side.

Questions
Which test strips are most accurate?
Accuracy depends on the full meter system, not just the strip. The FDA expects over-the-counter meters to read within 15% of lab values 95% of the time, so ask your doctor which system fits you.
Do test strips expire?
Yes. The date is printed next to the hourglass symbol on the box and vial. The FDA warns that expired strips can give incorrect results.
Can I use any strip with my meter?
No. Strips are made for specific meters. Check the meter name on the strip box before you buy.
Is it safe to buy used or pre-owned strips?
The FDA says not to buy pre-owned test strips. It recommends new, unopened vials from a pharmacy or the maker.
Have sealed strips you no longer use?
If you switched meters, sealed blood glucose test strips can still help someone. We buy sealed, unexpired boxes of Contour Next and Contour, Accu-Chek Aviva Plus, SmartView and Guide, FreeStyle Lite and OneTouch Ultra. We never charge a fee. Send a photo of the box and date for a free quote.
