She has been hospitalized since last Saturday, 11/16th. The blood test and urinalysis are testing whether or not her kidney is actually working or not. They can't tell me if she has had a kidney failure or not. This will be the 4th CBC chemistry and urinalysis, along with all the other tests they've done (i.e. x-ray plus radiologist consult). I have emailed Dr. Bruce Williams and am patiently waiting for his reply. I have also begun looking into other ferret specialists in town. Thanks for your help and support!
