Hi, I recently switched to bayer strips/meters because of an insurance change (from One Touch strips/meters used since '91) and I am very concerned about the accuracy of the readings. I have experienced wildly fluctuating readings from tests within a few seconds of each other, mostly to confirm readings which do not reflect how I actually feel. For example:
HI, then 279
LO, then 93, then 79
47, then 117, then 105
I never got HI or LO readings from my One Touch meters, so I test to confirm and the reading is wildly different!!! Is this happening to other people? Thanks.
The meter is only supposed to show "HI" if you are over 600, likewise it should only show "LO" if your BG is below 20.
All systems have a testing solution. It will tell you if the meter readings are accurate. Also, remember that meters can be off up to 40 points either way. I have tested first time at 200 and immediately again at 240. (I only retest when the reading is high, so...) Bayer can probably send you the solution.
You should be able to reset the high/low settings. Call the Bayer helpline--they probably get this question hourly and will be able to help
I hate to mess up this dicussion but control solutions only test meter against
pure calibrated samples of glucose D only and DO NOT PROVIDE A means to claibrate a meter in face of interferors to see if any issue.
Control solutions do work but in my mind prove very little as meter probably works fine against pure testing solutions.
There really should be an addition test solution with calibrated interferors/water/oxygen/hematocrat thrown in and then check meter.
I have been here too many times and learned nothing from the test solution other than my water, oxygen, interferor sugars, my hmatocrir were probably at end of range.
Some folks should be shot over the incompetent crap peddled over how all these meters read identical. Control solutions under this environment are usually useless.
The problem one has is the insurance company et all have been convinced to support a single meter type. (one might feel conned or given absolutely sweet deal to force all its members to use.)
Unless one knows what the operating ranges a meter works against reliably - water, oxygen, hematocratic rnages as well what interferors that meter rejects and how well ( And trying to find that data on present useless spec sheets provided customer detailing more important details on the case size, strip size and battery type proves hopeless)
The honest answer is that if you are "normal" and fit in middle of the ranges and liver/gut keeps the trick sugars contained until properly digested to glucose D; you should probably not have too much fun. If in my camp, it is real pain in derrier.
I definitely had large differences when I used OneTouch, but nothing like that! I've never tried Bayer.
I just switched to Accu-Chek from OneTouch because of an insurance change. I've never used anything else and it was definitely scary to change. I've found that Accu-Chek is more accurate for me than OneTouch, though. I don't get nearly as many false low readings now as I did six months ago.
Are there any other companies that your insurance company will let you use?
Accu Check gives me the most reliable results of anything I have used, so far.
Just proving that different meters work for different people - I'm pretty unhappy with my Accu Check and feel I got more reliable results from my FreeStyle which my insurance no longer covers.
Yes, the insurance will only cover Bayer unless you want to pay an arm and a leg for the "non-formulary" option...
I've definitely noticed that its numbers are usually higher than OneTouch. I've heard that before--that OneTouch results are artificially low. And with OneTouch, I'd get a 49 and then a number in the low 100's immediately after. I ALWAYS double-checked when my OneTouch meters told me I was low. I usually do with the Accu-Chek, too, because I'm not used to it yet, but I haven't seen much variability there.
Okay, just jinxed it! Accu-Chek told me I was 194, then 159, then 154. I double-checked with OneTouch, got 156. I knew I wasn't 194...
The one touch in the last released specs I Saw does reject other sugars in blood stream and reports only glucose D. No all meters do this. According to reports on a FDA page showed the Accucheck as still reporting on a sum of dugars in blood stream and not just Glucose D.
The One touch and some of the meters do a better job of filtering out non glucose D
I do not accept nor believe the complaint on reading articially low and have done comparisons of those meters against my cgms that did have a molecular filter to block non glucose D and those meters claimed as reading artificially low were in fact closer to my cgms readings.
