"PC" -Sorry you lost your little one. :-( >ALKP 177 IU >ALT 68 IU >BUN 20.8 MG/DL >CREA 00.0 MG/DL >GLU 296.9 MG/DL >TP 5.83 G/DL I'm not going to comment much on what normal values for ferrets are as that is outside my area of expertise. If anyone does have a list of 'normal' values for ferrets, maybe they could post it here. It might be a good thing to print out and put in with the emergency info in case the vet you rush to in the off hours isn't completely up on ferrets. There is more of an explanation on some of the blood values in the ferret FAQ part 5 section 12. To get a copy, send email to [log in to unmask] with GET ANSWERS PART5 FERRET as the text of the message. ALKP is Alkaline phosphatese, a liver enzyme. Higher than normal indicates abnormal liver function. ALT -??? I couldn't find this one. BUN - Blood Urea Nitrogen - indicator of kidney function. If high, the kidneys aren't filtering waste properly. Urea is the form of nitrogenous waste formed by our bodies, it's normally excreted in the urine. Can be affected by protein intake. Worth noting; according to the reference I used (_Outline_of Veterinary_Clinical_Pathology_, third edition 1978-it's old), kidney function tests only show up as abnormal when there is SEVERE kidney disease. We are talking 50% of the nephrons not working properly for detection. This is because the kidneys have a large reserve capacity-a lot of damage can occur and the animal can still filter blood normally. CREA - Createnine formed in the metabolism of muscle creatine and phosphocreatine, NOT affected by protein intake, age, sex, exercise or protein catabolism, along with the BUN value used as an indicator of kidney function. (Catabolism is self destructive, like a malnurished animal breaking down muscle tissue to get protein for metabolic purposes.) GLU - glucose levels, a measure of blood sugar. The FAQ states "A non-fasted blood glucose test might give values up to 207mg/dl, depending on when the ferret last ate." TP - total protein in blood. Depending on which proteins are high/low this can be an indicator of a number of things, including, but not limited to infections, liver disease, malnutrition, blood loss. . Normal values for dogs ranged from 3.32 to 7.7g/dl and appear to be age related; puppies under 12 weeks have lower values than older puppies or adults. -Ilena Ayala [Posted in FML issue 2169]
