My DME supplier keeps sending me a new Verio IQ meter every year, even though I’ve never asked for them. I DETEST the Verio IQ with a passion. It’s a complete and utter random number generator. You can test 5 times in a row with the same meter and get 5 wildly different results, well outside a 40% variance that would make sense for a meter that’s within FDA guidelines. (Meters are allowed to vary 20% in either direction from a laboratory value, so the farthest allowable extremes shouldn’t be more than 40% of the central value apart from one another)
It’s a shame, really, because LifeScan started out as the Cadillac of home testing. But it’s like they haven’t bothered to keep up with the times. They’re still sending out meters that are up to 1980’s standards, in a more modern design.
That said, there do seem to be a few more accurate meters in the lot. I’ve seen others rave about them and I’ve also seen them fare shockingly well in the the various meter comparison tests that have been made. (Maybe the manufacturers donated from primo lots?) I think there’s just a wide margin that rolls off the factory line. Some are terrible, and some are pretty good, and probably every range there in-between. Maybe the ones Byram healthcare chucks out for free just scored low in the quality testing phase.
I also suspect that while all meters are allowed a wide range of error, that people tend to prefer the ones that are more likely to yield numbers in the range they like. Such as, meters that have a tendency to read lower than true. So that might influence public opinion.
