I got the exam results today and I asked for a copy. The result for Phenobarbital its 8.6 which is in the sub-therapeutic level, and the sub-therapeutic level is <= 10 and the unit is ug/mL. I was looking at the copy and something that I wasnâ€[emoji]8482[/emoji]t explained is the ANTON GAP, and itâ€[emoji]8482[/emoji]s High 34, it should be between 13-27, the unit is mEq/L. I will ask the vet tomorrow but I was wondering if one of you know what this ANTOM GAP mean.
