Over the last few weeks I have noticed BS readings in the 90's to low 120's when I test my Blood. At first I thought I must be doing something right, but now I am wondering if my Glucose meter is working properly. Do glucose meters last only so long? Do they become less accurate within so many months? Should I have a backup meter to compare results? My meter is a One Touch Ultra mini that I have been using four about 4 months.
Thank you

I am recently diagnosed May 2010. My contour meter has been reading about 20 points lower than usual the last 3 days so today I decided to pull out the reli on meter (I am switching, my insurance doesn't cover the strips) I just bought and a one touch my doctor gave me. Anyway I tested the same drop of blood on all three meter and the reli on and the one touch said 120 and 121 but the contour said 87. I did it again and got about the same. I did a control solution test on the contour and it came out ok. What is up with this. Are meter this inaccurate. This is a big concern for me. Has anyone else had this happen.

Hi..I am new here too..and to Diabetes..I have type 2… sometimes I have to test two strips to get an accurate reading..I use the Freestyle Freedom Lite. I seem to know that a reading of 21 is NOT what it should be two hours after eating! Does anyone else have this meter? I test two times a day. two hours after breakfast, and two hours after supper. I am also trying to lose weight. I am so happy to be here!

Hello there! I am VERY familiar with the One Touch Meter Models that are out there. Each meter should have came with a control solution. If you are every in doubt of your meter, do a control test. Here is how you do a control test on a One Touch Meter:
1. Insert a test strip into the meter.
2. Place a drop of solution in the test strip. Like you would if you were going to check your BG.
3. Look on the bottle of test strips you are using. On the back of the bottle, there will be a control range number. If the number that comes up falls within that control range, your meter is okay.

if your meter did not come with the control solution, I would email One touch at They will mail you a bottle of this solution for you to check. From time to time, you will need to replace the batteries in your meter. It is also a good idea to always have a back up meter. BUT just in case you either forget your meter at home or the other one breaks on you. I would also make sure you do have extra batteries for your meter. Just in case the batteries do need to be replaced. You will be ready than for anything that may occur. One Touch has a very durable glucose testing meter system. In fact, I am currently using the One Touch PING insulin pump that uses their One Touch Ultra as my BG meter and remote. I lost count of how many times my meter has been dropped by me or someone in my house. Typically, the batteries in the meter can last from 4 months or longer. It will all depend on how frequent and the type of batteries you are using as well. I always use the Energizer Lithium batteries for both my meter and my insulin pump. I surely hope this has help you out. If you have any more questions, please drop me a message and I will respond back.

Thank you very much for the info on this meter. I had no idea that meters should come with a control solution. Unfortunately I am very new to all of this. I am at the point where" I don't know what I don't know." But I'm learning. Again Thank you!

UltraMini doesn't come with control solution anymore. Not sure if it ever did but definitely now they don't.

Meters will generally last years before needing to be replaced. Test strips and solution will expire. The strips have a use by date on them but that's only for unopened ones. Once opened they are only good for about 90 days, less if they are espoused to temperature swings. Also, altitude can mess with results and extreme heat or cold can mess with test strips. A low battery can also give incorrect results.

Why do you think you aren't doing a good job though?

Even though I watch what I eat and exercise, the results came rather quickly after many weeks of readings in the 140 to 160 range.

It's possible to see dramatic results within hours if you make the right diet and exercise changes. I think your meter is fine and you have just started to hit things right

Thanks for replying Harlan. This is the first time I am hearing about test solution. Should this have come wirh the meter?

The solution only comes with meters that specifically say on the box it's included. However, all you need to do is go to your local pharmacy and tell the pharmacy technician that you need solution for the type of meter you have. It usually runs around about $10—$12, and it comes in a small box with two vials.

I have an Advanced meter. All I do is call them up they send me the testing solution for free. They also told me that my meter is old and send me a new for free. Ony using the new one will coast mor because the needle that you use to get blood can only be used once it is a drum that hold so many. I tested my old meter and it was ok. call ACCU-Check at 1-800-858-8072 customer service.
