Hi Elise. Sorry to hear that your meters are giving you trouble. This is only anecdotal, but our vet had me borrow an AlphaTrak to compare some tests. At numbers above 200, it was pretty off from my ReliOn, maybe by 40-60 points. But I got one test where the ReliOn said 52 and the AlphaTrak said 68 on the dot. I had another where the ReliOn said 72 and the AlphaTrak said 100. It seemed like in lower numbers where Max likes to hang out, the meter comparisons matched the way we'd expect them to. Maybe your vet would loan you an AlphaTrak and some strips to compare? Sending vines for your mom.
