You could ask on YT for vet recommendations in your state.

The liver enzymes in a basic blood panel are sometimes up with liver shunt but that isn't always the case and I would not count on that as an indication. Bile acids testing is the way to go to rule this out.

Fasting used to be recommended but Dr. Center has since says it isn't necessary. Most vets require it though, so you might just go this way and avoid the debate. It is okay to fast them as long as you aren't worried about hypo.
