Meter Accuracy

I think we have all seen a complaint or two about meter accuracy. Some of us (*cough Bennet *cough) even have signs to express our displeasure with the current standards.

my version


Usually my meter matches up “close enough” to my CGM that I feel pretty confident about the results. One morning a few days ago told a different story.

I was driving to work and checking my blood sugar for my breakfast bolus. I usually take that opportunity to give my CGM a value for calibration as well, so I clicked on the DexCom to check my graph there. I don’t remember the exact number it was showing, but I know I had an arrow headed east (meaning the number is relatively stable) and a result in the 140s-150s.

I think that’s why I was so surprised when I tested and saw a 77 on my meter.

Testing and driving is always a challenge, but now I had to test again to break the tie between the DexCom and the UltraLink.

Two minutes later and my blood glucose is now 100 points different?

 Now what do I trust? The DexCom, the first meter result, or the second meter result?

At the next red light, I tested a third time.



Three test strips down. $3 wasted. Three times the aggravation.

I’m siding with Bennet on this one.

    When I used the UltraLink I had nothing but readings that were off to my Dexcom. (And a second or third test would result in a reading much closer to the Dex) I stopped using it and will not use that meter again.

    When I was using the Ping pump and meter, I found less instances of such “off” readings. But I still had a fair share. And I did countless multiple tests to ensure I was getting the right reading. It drives me crazy.

    I just started trying out the Accu-chek Aviva meter and have to say that it’s been pretty darn close to the Dexcom. It’s only been a week but I’m feeling confident enough with it about the results I’m getting that I’m thinking of switching permanently.

    The variations infuriate me. I side with Bennet too!

    Hahaha! I just did a video where I tested with two different meters. And then I tested twice on my OneTouch. Watch it here:

    I have NO IDEA where that second sign was photoshopped. The first one is legit. #MyStoryAndIAmStickingToIt.

    Here is how to put the meter in its place:

    This drives me crazy! The tools we use to manage diabetes really need to be accurate.

    That settles it. No more using the Link. Forget that meter. I will use another from now on. Now to get my doc to change my prescription!

    Sara, are you using the new OneTouch strips? OneTouch claims they’re more accurate. This kind of behavior is why I changed from OneTouch and now use a WaveSense meter. I really like their meters, just a satisfied customer. I’ve also enjoyed the Bayer Contour USB and use it as a backup meter — one big advantage of the contour is no batteries needed.
