Almost two weeks ago, I posted about BG meter accuracy issues I’ve been having. I received the new replacement meter from One Touch as promised, last Tuesday, and I continued my comparison between the Ping and the Freestyle Lite. Unfortunately with the same results. On average, the Ping was 19% lower in readings, sometimes much more than that. Now I know what you’re thinking – the FDA has a standard of meter accuracy within 20% and that difference is within that standard. So maybe technically there is nothing “wrong” with the Ping meter. However I am not comfortable with that big of a difference. Just yesterday my first reading on the Ping read 101 mg/dL. Since my Dexcom read higher than that (and I’ve run out of Lite strips) I retested. This time it read 185 mg/dL, more in line with the Dexcom. That’s a 45% difference! Like I mentioned in my last post, that 19% variance is equivalent to one whole a1c percent! That is huge. And I truly believe that it has lead to some disconnect I’ve had between what I thought my BG readings are and what my a1c is.
I’ve made the decision to switch from the One Touch meter to the Freestyle Lite. It’s not a decision I was happy to make actually. I’ve depended on One Touch for quite some time and am sorry that their product wasn’t more reliable for me. And I’m not saying it’s a bad product either. My conclusion was strictly made on my own personal experience. I am thankful to have the knowledge and resources available in order to make this decision that is so imperative to my health. Part of my reason for sharing this story is to inform others who may not be aware that things like this can happen. Most importantly, the FDA seriously needs to work on improving that 20% accuracy standard. And ASAP. Our BG readings are nothing to mess with.
And a thank you to Edgepark for being so accomodating in getting my strips exchanged.
