Full article is here: When "Normal" Dogs Have Abnormal Liver Enzymes.While the very purpose of testing the liver enzymes is early recognition of problems to provide opportunities for earlier and more meaningful intervention, the veterinary practitioner is challenged to determine if the abnormal result really does constitute a problem. Veterinary internists are often asked to consult about middle aged to older dogs that have moderately elevated serum levels of alkaline phosphatase (ALK, ALP, SAP), a commonly measured liver enzyme.
If pets appear otherwise well, it is exceedingly important to verify the abnormal result before pursuing it as a potential problem. In other words, the veterinarian will need to make sure that the abnormality shows up on re-tests and not just a fluke. Repeating the lab test in one to two weeks with ideal patient preparation is common. Once the abnormality is verified, the veterinarian can try to determine whether the patient’s health is in danger.
