Firstly, I am not a vet, just a vet student. Just looking at the values without any case history or physical exam, it appears to me that the liver values (ALT and ALP) can indicate a liver issue. The creatinine and BUN values indicate azotemia which can be caused by pre renal, renal or post renal causes. Dehydration is a common cause for pre renal azotemia, but from the HCT values, I would GUESS the ferret was hydrated Further tests specific for kidney function can be pursued to help rule out/in causes for the azotemia. Here is a link that may better explain the values to you. Hope this helps, like I said I'm not a vet and have no history to really base his numbers as to what might be the cause. I wish the both of you the best. http://www.ferretuniverse.com/health/cbc.asp Tasha Krause KSU CVM Class of 2013 [Posted in FML 7316]
