So you went to the vet for 'blood work" so what does all those numbers mean??
Kidney function BUN is a common test of kidney function. Unfortunately, it’s also affected by other factors
Creatinine is a much more sensitive test of kidney dysfunction. Even small elevations of this enzyme can indicate signiﬁcant kidney problems
Urinalysis Many different pieces of information can be derived from a urinalysis. One of the most important deals with kidney function – it’s called the urine speciﬁc gravity. If kidney function deteriorates, they are less able to produce dilute or concentrated urine, resulting in an abnormal speciﬁc gravity.
Liver function The best test for diagnosing liver disease is the ALT (alanine transaminase) test (formerly called SGPT).
NOTE: normal may not be normal for your pet. While vets are trained and most are very contentious, never hesitate to ask questions
