I have been using one touch products since I was dx in 2002. I was given a new Freestyle Lite and I tried it out right after the one touch. I noticed that the one touch was about 20mg/dl lower than the Freestyle. This morning I went to the endo and I tested with the one touch right before they tested me with their accucheck and again it was about 20mg/dl lower. Has anyone else had problems with lower readings from one touch meters?

Here is the website that I got the meter and the teststrips from:)

I hope that copied ok..it was long! If you go to the main webpage and just clickon monitors it will take you to them and teststrips too. I love this company when things are downhill financially.(it's a easyCheck by HomeAide and the teststrips are $13.79. the monitor is 25 and change.

Check out the Maxima meter from Hocks Pharmacy (www.hocks.com)

Meter

$9.95

Test strips
50 for 16.95

This is reported by Mendosa as VERY accurate!!! (www.mendosa.com)
Brian,

Your Endo must be referring to the paper this study they released in 2006: http://www.lifescan.com/pdf/uk/AW_087-308A.pdf

Using the Consensus Error Grid, they note that 98.5% of the Test Results fell into "Zone A: No effect on clinical action." What it fails to explain is that Zone A means 20% accuracy. Meaning if you were really at 200 and the meter gave you 160 or 240, it is still considered clinically accurate.

Whether or not you believe that is accurate enough is completely up to you. How about 15%, 10% and 5% accuracy? You'd have hard time finding many meter companies willing to publish a paper on those standards.
Hey Kristin,

Do you use the Maxima AST meter? $16.95 for 50 strips is pretty cheap. I think that I really want to like the WaveSense meters but with questions around the device's accuracy, I haven't purchased one yet to play with. I was at the local JDRF walk this summer and hoped to play with new meters, sadly, the space was smaller so no meter companies. I wish the ADA would have their Diabetes Expo in the DC area again. While helpful, it was great to have the chance to talk to meter makers and give them suggestions (I've review computer hardware for a few big publications so I always seem to have far too many ideas.)
Sorry just saw this message.

I don't use the Maxima meter, but my dad does.

I suggested it for him, based on David Mendosa's report that it is highly accurate! See this article.
Has anyone found any programs among those offered by the meter companies that you think are really good? Like those web sites they offer with recipes, fitness journals and that sort of thing -- or that mail you information or send you emails? I have a blog and am looking for anything that people think is really helpful. Or that you think is inappropriate or not helpful. Thanks
Accu-Chek has a program called "Inner Circle" which provides online logbooks and other support. Abbott's Freestyle Promise program provides free meter updates, support, and training, and includes co-payment assistance for test strips. I believe Bayer and Lifescan also have user-support communities on their sites as well.
I have used three meters from ONETOUCH and two ACCU-CHEK's. The ONETouch meters all read about 10 to 15 mg/dl low while the accu-cheks were all on target and only a 2mg/dl difference between the accu-chek advantage and the avia.
during the past 6 months, I've done a lot of research on meter accuracy. I am convinced the Flash, the accu-chek aviva and the agamatrix Keynote are the most accurate meters available at this time. I am ordering the agamatrix for myself and my wife because of its size, accuracy, its backlit display and inexpensive strips.

If I were to suggest any enhancements for the agamatrix it would be multiple strips in a wheel or drum and an attached lancing device also with a wheel or drum of spare lancets. A further enhancement would be reminder alarms with text and an insulin dose calculator for bolus/basal meds.
Danny,
Umm... did you actually try using a Keynote before deciding that it was the most accurate meter available? The only thing that matters is how well the meter that you actually have works. Agamatrix does a good job of pushing the accuracy of their meter, but I was badly let down by the 2 Keynotes I used and had calibrated against lab tests. Both were reading more than 20% high. Maybe I just got stuck with 2 lemons, but I doubt it, and I'm not giving them a 3rd chance. I have lots of meters, from other companies, that are much more accurate.

Good luck with your meters.
I'm in the process of doing side-by-sides of a number of meters (check my blog). So far, the Keynote has been running consistently higher than the other meters. It's a small scale test with relatively few data points...
Hopefully this may help in sorting out your meter accuracy question. I sold inpatient glucose monitoring systems to hospitals for many years. In the hospital environment, accuracy and precision is always evaluated usually through a lab comparison study before a product is selected to do blood sugars on hospitalized people with diabetes. Most of what we know from the hospital environment also applies to consumer blood glucose monitors. The first rule of thumb is that you can't really compare a reading you get from one meter to the a reading you get on another meter. The only true measure of accuracy is to compare your meter glucose result to a lab glucose result. Most meters have a slight bias either low or high to the lab. For meters that have a low bias the agrument could be made that you will rarely miss hypoglycemia. Here's an example that may help illustrate this for you. Let's say you have a lab glucose done and the lab value is 100 mg/dl. You test your blood sugar with Meter A and the value is 90 mg/dl. You then test your blood sugar with meter B and your value is 110 mg/dl. Both meters are within 10 mg/dl of the lab value yet there is a 20 mg/dl spread between the two meter values. You certainly can't say one meter performed better than the other in comparison to the lab reading. In fact both performed exactly the same. I hope that helps!
Julie, I'm so glad you posted this. Most people don't understand that meter accuracy should ALWAYS be compared to a lab standard, NOT another meter. A good number of meters out there also have a low bias to avoid hypos. Until meters are able to improve their accuracy to be more exact, lower readings are generally safer. What results though is higher averages of readings leading to higher A1Cs than would be expected. Please correct me if I'm wrong about this.
