How irritating!

Whilst overseas, in a third world country, my iBG Star meter died a fairly rapid, but total death. The impact was that for a period of around a week I could only coax one test a day out of the thing, then a period of no testing at all. This was incredibly frustrating, but at least I had a decent idea of what I could and couldn't eat, and I just stuck with “reliable” foods for the barren period.


On Wednesday I got back to UK and I had an SD Codefree meter waiting for me, as I feared there might be a couple of days until Sanofi got their replacement out to me. Testing with the SD has been pretty straightforward and it return results a tiny bit lower (maybe just 0.1 or 0.2) than I might have expected on my original BG Star, but I put that down to the much colder weather and maybe even a bit of jet lag; although historically, I found jet lag elevated my numbers.


Anyway, having charged up the new iBG meter, I started using it this morning, and now I'm a bit bewildered. Pre-breakfast I only used the SD, which returned 4.6. Two hours after breakfast, the SD returned 5.1 and the iBG 5.4. (I was fine with that.) Before lunch, the SD 5.0, and iBG5.9. An immediate iBG retest returned 4.9, so I concluded a fluke, as I had just squeezed a little more blood from the original puncture which the SD read as 5.0. That felt close enough to comfort me. Post lunch, SD recorded 4.7, and iBG 6.4. On retesting with both meters I had SD 4.8 and iBG 6.1. Both only slightly different, but one up, and one down, but still a fair way adrift from each other.


I have used the control solution twice today on the iBG, with returns of 8.1 and 8.8 respectively. The latter reading is outside Sanofi's tolerances of 5.0 - 8.3.


To be honest I feel a bit bewildered and inclined to trust the SD more than the iBG as it is consistent and pretty well aligned to the readings I was seeing before the enforced break from testing. Of course, the alternative is I'm being seduced by the SD's lower numbers, as I dislike numbers of a larger persuasion!


Fortunately, I had the bloods taken yesterday for my 3 month post-diagnosis HBA1c, so at least I'm not in this bewildered state immediately before that, but it's quite unsettling. Hopefully in a few days I will have the results which may guide me further.


What feedback does the collective have for me? Has anyone else had consistency issues with a meter; whether the iBG Star or another one? I do like the size of the tiny iBG, and its seamless synchronisation with the App, but it's no use being cute if it isn't reliable.

(Apologies for War and Peace.)
 
I read a post recently where the chap had different reading and they were substantially different. It shocked me... but there seems to be a margin of error within a reasonable range. So now, as I have several meters I retest if I get a reading that I don't like. Otherwise I just trust my meter, it's easier that way, for me at any rate. But, just to clarify, I don't have particularly high readings so it;s not so important. But for others it might be crucial ...

How maddening. It's a horrible feeling when you can't trust equipment.

I take my meter along with me when I have to have bloods done and do a finger prick just before they put in the needle. That was I can compare my meter with the official results. Of course, that only gives a 6-monthly check, but I've found it useful to show the record to health professionals who disregard a patient's own readings as unreliable or irrelevant.

What a great idea, Kate. I'll be making use of that strategy when/if the time arrives. :woot:
