The Problem With Generic Test Strips


In concept, generic blood glucose test strips sound like a great idea. Made by 3rd party manufacturers (i.e. a company other than the one that makes your meter), they often (claim to) work with a variety of different meters, and tend to be much less expensive than their counterparts. Given that big-name test strips can cost $1 to $1.50 a pop, it makes sense that people with diabetes (not to mention insurance companies and government payers) would be eager for a cheaper solution. 

But there’s a problem: those cost savings are only relevant if the generic test strips are accurate. If they’re not accurate, then you may miscalculate your insulin dose. And if you miscalculate your insulin dose, you could die.

(To put it a different way, if a blood glucose test strip doesn’t accurately measure your blood glucose, then it’s not technically a blood glucose test strip. You might as well read tea leaves.) 

Personally, I can’t wrap my head around the fact that there is currently no system in place to ensure that test strips that have been cleared by the FDA for sale continue to meet those accuracy standards after they’re on the market. (But it’s true: there’s not.) 

I also can’t get over the fact that Medicare continues to insist that there have been no negative effects of its recently implemented competitive bidding program for mail-order diabetes supplies — despite evidence (for example, this study from the American Association of Diabetes Educators) clearly indicating that the program is restricting people’s access to blood glucose testing supplies, and pushing them — often against their will — toward problematic generic meters and strips. (Important note: they’re not allowed to do this! Scroll down on this page for more information.)

But in the rare moment when I think to myself, “Hey, Catherine. Maybe it’s not such a big deal!” something always seems to come up to snap me out of my reverie. An example of this happened just yesterday, when I received a safety notice from the FDA about Shasta Technologies’ GenStrip Blood Glucose Test Strips. (The company previously received an FDA warning letter.) If I may quote: 

“During a recent inspection of Shasta Technologies LLC, the FDA found extensive violations of federal regulations intended to assure the quality of products in the manufacturing of GenStrip Test Strips. . . At an inspection earlier this year, and documented in an April 2014 warning letter, the FDA found that Shasta Technologies did not have in place many of the requirements of a quality system. Without assurance of an adequate quality system, the FDA believes that the strips could report incorrect blood glucose levels. . . . To date, the company has been unwilling to voluntarily recall their test strips, resulting in their continued availability. The FDA recommends that use of Shasta Technologies, LLC GenStrip Test Strips be discontinued.

(Emphasis mine.)


This is not the first instance where third-party generic test strips (or low-cost meters) have been found to be problematic. (See also: this weird language from the FDA for a meter cleared last December.)  Indeed, Mike Hoskins recently did a great feature about the issue, which, given yesterday’s notice, has proved to be disturbingly prophetic. 

The company that now makes the GenStrip test strips issued a response to the FDA’s notice today, essentially claiming that the problems have been solved, those particular strips will be replaced at no charge, and that a new, rebranded version (of the same product) is soon to be launched that presumably will not have accuracy issues. Frankly, I’ll believe it when I see it — and also, as far as I can tell, this is not an actual recall, as might seem to be appropriate given the potentially deadly consequences, but rather an offer for proactive and educated customers to get replacements. 

It’s worth stressing here that the cost of test strips is obviously quite high, and that there is a need for lower-cost solutions. But cost does not — and cannot — trump accuracy. 

If you agree that accuracy is an important issue, and that the makers of 3rd party strips should be held directly accountable for the quality and accuracy of their products, please consider adding a comment to the FDA’s Draft Guidance on Blood Glucose Meters, which is open until an extended deadline of May 7th. 

For more information (and suggested comments), visit (And here are my previous suggestions for other comments you might want to add, in addition to whatever you want to say about the issue of 3rd party strips.)

You can also learn more about the draft guidance as a whole by watching the FDA’s patient network’s March 31st live-chat on the subject (the first ever of its kind!) in which the FDA’s Courtney Lias and Helene Clayton-Jeter sat down with creator Bennet Dunlap to have an informal conversation about what the guidance says and what the agency would like feedback from the public about. 

Also, consider leaving a review (referencing or directly quoting from the FDA’s notice) on the Amazon page for the meters and strips in question — it could help save people’s lives. (Here’s one example — but there are many other test strips made by the same company.) People need to know about these quality concerns, and (especially since the company itself is not doing a recall), Amazon is a great way to spread the word.

Again, the deadline for FDA comments is May 7th (and it only takes a few minutes). Goodness knows the 3rd party manufacturers are going to make their opinions known. Shouldn’t we do the same?

I have been purchasing these test strips because Medicaid will only pay for testing once daily. I need to test 3 times daily to maintain a good blood count. I just received another shipment with a totally different code (4) instead of the usual 49 and I’ve checked my blood sugar three times today and received the same reading. Not too happy with these results since I bought 200 strips.

One alternative not mentioned is Freestyle Precision Neo. Regular Freestyle strips are among the highest, but this one is different. 50 Precision Neo strips are about $22 at the highest, some places 18. More like store brand. The meter is about $25 at Walgreens. (these prices may be a little lower ordered off Amazon). It is slightly higher quality,easier to use than store brands. Abbott intended this one to be OTC and less expensive. I recently found out there is software and it can be uploaded to that as well(looked at mine and the port was there). Available from Walgreens,… Read more »

Catherine, may I say that your conclusions are just that, your conclusions. On what scientific data do you base your conclusions on? I started buying my One Touch test strips on Ebay two years ago. Recently I bought 200 strips for less than fourty dollars. They were a mixed group, none in the original box, two bottles were a year out of date. I bought one or two bottles of twenty five strips at the local walgreens and have been compring the factory fresh strips against the ones I got on Ebay. I used the walgreens strips as a control… Read more »

Thanks for the info. I’ve been using a generic strip (not sure which one), but I was feeling really good about my numbers until I got my A1C test back and was quite a bit higher than I expected it to be. Wondered if it was the strips. I took 3 separate tests this morning, 1 right after the other, and each one was a little higher than the previous. Hmmm. Going to test my meter & strip against my Father’s unit to see the difference.

The FDA is like Trump. These strips are totally inaccurate. Each readings done at the same time are all over the place.

I understand the need to be accurate; it’s as bad as using expired ones, but is there any discernible reason why, say One Touch, should cost $50, even with insurance, for 50 strips; it’s no wonder people seek cheaper alternatives. I’m Type 2, and I’ve gone through three different types of strips and meters, and I’ve just got another one (again, a One Touch), since meters apparently over 5 years old need changed. Someone needs to seek an FDA approved alternative, that’s less expensive,and maybe, just maybe, the people who make One Touch, Precision Extra, or Accu-Chek, and others, may… Read more »


Thanks for the article as I see this as a legitimate concern. For years I have used One Touch Ultra 2 and Mini equipment with their strips. I can’t recall ever having a notable discrepancy between the meter tests and lab blood draws. A few days ago I was forced to use the GenStrip 50 strips because my pharmacy no longer carries the OneTouch strips. They definitely read high the majority of the time by 15 to 20+ points (though in one case they read lower than the One Touch strips). The night I started using them I had a… Read more »


Genstrips are now being manufactured by a different company than the one the FDA complained about.
Several reviews for different but similar products on Amazon have stated the current strips are quite accurate.
I just purchased a One Touch Ultra 2 meter and only have their strips. My guess is it is reading about 30-40 points LOW after a meal. I will test more in the next day or two, but I am not happy right now.

I can’t help but get the feeling that this message is funded by the manufacturers of the non-generic strips that are sold for $1.50 despite costing 2-3 cents to produce (according to the New York Times).  I am all for lobbying the FDA to ensure quality control for ALL test strips — but why is this article urging us to lobby only for quality control on 3rd party control strips (while presumably giving the mainstream companies with the 1000% mark-up a pass)? I would also note that the author of the article attempts to leave the reader with the impression… Read more »
