started Bryant on ProZink on Wed! 1u x2 testing on a Alphatrak2. Twice a day before each feeding and shot. His lowest number in that time was 510, the highest was 683( the very first day) his number is consistent now for the past 4 days, at 500-550. His lowest # was 421 but that was the first day after diagnosis before stating treatment! I'm going to consult my vet tomorrow AM! I have ordered more test strips to do a series as I am home for a few days this week, to get a look at where his drop off number is. I'm thinking that his dosage may need to be increased? How much time in the initial stages do you normally allow to know the numbers are accurate? I've started a spreadsheet today to be able to track online and share the info moving forward. I've changed his food now for the past 5 days now to the low carb FF & Friskies.
