Some of you may have read about the FDA's recent warning about the inaccuracy of certain test strips while taking certain medications.  Honestly, I didn't pay much attention since I already accept they are inaccurate and I wasn't using any of the interfering products mentioned by the FDA.  However, since it affects anyone receiving dialysis I realized I might be negligent in dismissing the problem.

Today, Diabetes in Control published more information on the topic including stating that Wavesense (Agamatrix) products are of a new technology and thus do not have this interference problem.  Bayer also says their meters don't use the old technology.  HOWEVER - several meterrs that are used to calibrate CGMSs do use this older, inaccurate technology.  So ... use a product that is inaccurate to calibrate another inaccurate product and you get double inaccurate.  Nice.  This article is primarily about the few number of people affected by the problem but nonetheless being an informed consumer is forewarned. 

I've always known that many sweeteners (primarily sugar alcohol) can mess up a blood sugar.  This article states particular products that inaccurately skew blood sugar results.

I've also heard people with kidney problems say their blood sugar drops quite a bit and believe it's because of the kidney problems.  They have different sensitivity levels.  Scratch the head.  Well, apparently that's only partially true.  It seems that the drugs they are taking cause the meters to read incorrectly and thus they OD on insulin in an attempt to correct a supposed high.  So it's not the kidney problems or the insulin or their sensitivity.  It's the inaccuracy of the meters.  Big oops! 

Again, I realize apparently small numbers of people are affected by this but it is another reason to demand not request that meter manufacturers spend some of that $1-$1.25 per test strip and find new technology that works.  AgaMatrix has .... why can't the others?

Contrary to assertions that in-home and in doctor's office A1C tests are accurate enough, according to this article in Endocrine Today, A1CNow and A1CNow+ are not proven to be accurate enough for "routine use."

What I read clearly is that there are studies that absolutely say they are not good enough to be used for regular use.  I also read that a "redo" study was done by the manufacturer (Bayer) and then it passed but this article can not say the product was actually improved - just that it passed the second time around.  Warning signals go up in my mind.  Having worked for a company that had to MAKE products pass certain government tests and knowing what they will do to get them to pass, I'd put money on it, they rigged/manipulated the testing and they did not improve the accuracy of the product at all. 

These tests have to be certified in order to be covered by Medicare and by the National Glycohemoglobin Standardization Program.  They also have their own Medicare billing codes, separate from lab A1C billing codes - thus, many insurers are paying for two per visit!  That's fine to determine if the in-office tests are accurate but double billing insurers will cost us all in premium increases.  I prefer to wait the few hours it takes a hospital lab to do my A1C.  I choose to do it a few days before my appointment so the doctor has the results before I arrive.  My hospital lab is open 24/7 so i can do it on my schedule.

In conclusion, I will continue to demand in lab A1C testing only. 

Happy reading.
