I'm sorry in advance for typos.

It sounds like you have a good vet. Preop blood work indicated that her liver may be under stress. Bile acid testing gives more information about how the liver is functioning. Your girl's result is high, but nothing crazy.

There is a long list of things that can cause liver function issues. Somewhat commonly in yorkies is liver shunt which you could google. As a general rule though, post prandial bile acids are higher than your girl's when LS is present. I wouldn't worry too much that this is the problem. Micro vascular dysplasia (mvd) is also common. This is a sort of microscopic shunting in the liver. The bile acids often fall in this number range when mvd is present. This would be medically managed.

First thing to do is talk to the vet about the next step. The best option is probably a consult with an internal medicine specialist to try and get a diagnosis.

Sometimes drugs and such can make the bike aids go up also. Our vet may just want to retest in a month. Different vets' protocols vary. It may be a big problem but most likely it's not a huge deal. Try to relax until you talk to the vet. My dog's bike acids have been almost double that and she does fine.

Common scenario..although certainly not the only one..is a yorkietalk that has post bile acids in the 40-90ish range being diagnosed with mvd after specialist consult (a biopsy is needed for absolutely diagnosis but skipped a lot of times). They are managed for life on supplements and certain foods and particular attention is paid to drugs prescribed because they can be hard on the liver. They live long and happy lives.

So talk to your vet and don't focus on worst case scenario because that is likely not the case.

That ALT is a very low high. It is something to keep an eye on but no reason to panic.

I'm sorry that was a big ramble.
