Good Morning, Everyone!

I have a question that I am hoping I can get some input on about meters. In the past year since being diagnosed with Type 2 Diabetes I have collected three meters. I find that there is a huge discrepancy between all three meters…about 30 points.

Does anyone find one meter is more accurate than another? I have used control solution on all of them, my strips are fine…I am just puzzled.

Thanks so much for your time!

First of all Alcohol Wipes and Hand Sanitizers that contain alcohol will change your results no matter what kind of meter you use. Wash hands in warm water prior to testing and do not use any kind of soap or hand lotion that is fruity. Fruit essence can change your readings. I learned this in a diabetes education class and noticed a change once I stopped wiping my finger with alcohol. I noticed that when the nurse at the doctors office pricks my finger she does not use an alcohol wipe.

Meters can also react to high humidity and extreme cold. Meters should not be left in glove boxes in your car or in places where they are in direct sunlight.

Reading the instructions that come with the meter will tell you how to care for it so that your readings are as close to accurate as possible.

So far I have in total used 3 meters too. All similar results but a few times, I noticed my blood was really low (a 45 etc). I called Bayer and accuchek and they told me these things can affect your readings.

- Must clean area before pricking
- If using alcohol swabs, U MUST WAIT FOR IT TO DRY
- never mix test strips together (example: if you have 4 test strips left in a bottle, do not add in more strips into the same bottle because the bottles have different lot #'s and expiration dates)

IF you still think your meter is defective, you should call the manufacturer and get a new one.

Type1Lou mentioned different fingers and hands but also if you swab your finger with alcohol or have on a fruity hand lotion that can cause a variation also.

In addition to the allowable 20% variance mentionned, if you use different fingers/hands to test in your comparison, that may also be a factor. I recently changed from a One Touch meter to a Bayer Contour Next link meter because it is reputed to be more accurate. I haven't had it long enough or done enough comparisons to make a statement on the accuracy based on my experience.

I agree on the vario IQ. It does much better than a big box store brand. The vario also links to your computer to track all of your data.

You may want to use one for a couple weeks and log your readings and how you feel. Then switch it up and try another one.
I like my meter because with my insulin dose it feel the best by going with it's readings. (T1D)

Meters are going to vary based on manufacturer but with the FDA guidelines of a 20% +/- era margin, they usually are not too far off. I use one meter and it is always within the 20%+/- error margin. I never switch back and forth.

Thanks…that is what I try to do but a 20% error just seems like lots to me. I will just keep doing what I am doing and keep my fingers crossed that my A1C continues its downward drop. Also, somewhere are there guidelines that tell you, let's say, your BG average for 90 days is 128…what would this equate to in your A1C number? Or, what is the criteria used for A1C?

I have a few different meters also. The differences that you are seeing are fairly typical among different meters. The FDA allows a +/- 20% error margin with test meters. Meters are simply a tool to help monitor and get a reasonable idea or a ball park figure of what your blood glucose is doing. I use a meter that comes reasonably close to my lab results.
