I WAS a big fan of the Bayer test until just recently. I supplemented my 4-6 month office tests so I wouldn’t go more than say 6 weeks without a test (I was diagnosed a year ago). So the tests matched up the first few times, but my last test, I got a reading 0.7 higher than I had been. Pretty significant change in 5 weeks, but figured that maybe i slipped a bit.
5 weeks later, I tried to test again, and got a dead meter in my kit. Called the help line, and they asked for the lot number and said they might want me to send the meter in. After a brief hold to check with if the lot was suspect, they said, don’t worry about sending it in, just throw it out and we will send you a coupon for a new box. I hung up thinking, “did they already know this was a bad lot?” and what type of quality control do they have? Also a bit miffed that I am on the hook for a trip to the store, and about $2.50 in sales tax, when they screwed up my testing schedule with what they seemed to accept was a defective product. I could have bought a new one that day and used the coupon for later, but I read so much about their questionable accuracy, that I wasn’t sure that I would use them going forward.
So coupon comes, get my test, and I go from a hightest ever 6.4 to a lowest ever 5.4 in six weeks. Since I was not experiencing hypos, I am highly suspect of the number. I had normally hovered at 5.6 when I was more focused. The tests materials state that their version of accuracy is within +/- 0.5 points. So is it likely that I was around 6.9 and these two test were on the extreme ends of the acceptable testing levels – possibly – but then what is their usefulness. I don’t believe the last one because it was sooooo low, and the high one left me feeling that I fell off the wagon for a month.
So as of now, I am done with these tests. Maybe if I my A1c was much higher, flucuated alot, and only got labs done once, maybe twice, a year, I would supplement with the the Bayer. I think you would do better to review your testing logs to look for trends than to base any decision on these tests. The tests are about $10 to $15 a piece, but i think it is only $20-40 to get a lab to give an accurate reading that can actually be acted upon. If you are thinking that you might be either a 6 or a 10, then maybe knowing you are around 7ish is helpful. Just not for me.
