Hi! Em had her first phenobarbital level done on Thursday and it was '22'. My vet said it should be near 30. vet said she would need an increase dose by the neurologist. I'll call her tomorrow. She is still having episodes, but is much better on the whole. I'll be glad when we can get to a correct level, as these blood tests are expensive. My vet is VERY good about charging me just for the blood test, and not an office visit. I'll let you know what she says. Sue
