Lab Values and Resp. Infections

Question
Hi again!   Sorry to take up all of your time! ;) I'm the owner of Paulie (8y.o.), I had asked a question regarding oral dermatitis on 11/4.

Paulie is still hopping and around and eating well, and doesn't show any signs of pain (abdomen, face) but Tuesday I noticed him starting to sneeze and have some nasal discharge.  I had taken him to another vet, who checked out his teeth and saw no issues in his mouth.  However, she was quite concerned with his decrease in weight, and why he has another resp issue.  The vet started questioning: him having a decrease in immunity which could be leading to his infections, and his losing weight despite his voracious eating habits.  Unfortunately I couldn't really afford the realllly expensive ultrasound or xray, so I had blood work done on him.  The vet didn't seem very concerned about the results, but as I did some research on lab values in rabbits I grew a bit suspicious.  

Here is a breakdown of his abnormal values:
Eosinophils: 116 (H)
Globulin: 2.4 (L)
ALT: 66 (H)
Alk Phos: 46 (H)
Phosphorus: 2.7 (L)
Calcium: 16.3 (H)

A lot of those labs point to liver disease, which concerns me a bit. Is there anything to do for a rabbit with suspected liver disease?  He's currently on Baytril 22.7/day, and hopefully if it's bacterial that will help it.  In regards to his weight, too many pellets causes GI issues, so what can I give him to help his weight that won't be likely to cause issues? And my last question (for now..I promise), is with his calcium level that high, should I have him on a low calcium diet?

Once again, Paulie and I thank you!

Answer
Dear Shalyn,

I don't see any values for B.U.N. or creatinine, which would tell how the kidneys are doing.  But liver problems can result from any number of things, including chronic infection.  The antibiotics are a good idea, just in case.  

His calcium levels are actually not that high for a rabbit; we see this rather commonly.  Rabbits with metabolic bone disease actually tend to have *lower* than normal serum Ca++ levels (12 or so), and this is a greater concern.

Don't reduce his calcium unless you're feeding him things like spinach (the only green I don't give my bunnies); we've found again and again that reducing dietary Ca++ does little or nothing to change serum blood levels.

I still think the kidneys could be an issue, as renal disease can cause oral ulcerations *and* weight loss.
