Boy do I feel stupid - but it appears for the last couple weeks (unclear how long) the Alpha Trak 2 meter was set for the wrong strip number. It's supposed to be 8, to match the strips calibrated for cats. I think it was 30-something but I can't be sure. The vet noticed it today. I don't know how it got changed or why I didn't notice it, but that's neither here nor there. Can I infer anything about how this might have affected the numbers, up or down? Thanks!
