I've been testing when I can, but I only get a chance to check before and after work. Fortunately, Chino doesn't have a history of throwing ketones. I waited for him to use the litterbox this morning but he only went #2, so I was unable to check before it was time to start work.
I only tested with both meters the last time he saw green, so I could show the vet that he wasn't anywhere near hypoglycemic, but before I started home testing, I ate something high carb and tested my own BG with the Relion Confirm, the Nova Max Plus, and the AlphaTrak 2. The human meters showed 221/222 and the AT2 showed 334, so I know that when I get a number in the low 200s, the real BG is in the 300s.
