Okay I called my vet that did Diggy's Bile Acid. They said this.
Every machine is diffrent where they get thier ranges is from an average of readings/tests.

The particular Machine my vet used has the following range

0-12 Normal
13-25 Retest
25+ Retest and treat as Compromised Liver.

Diggy's results were 5 pre 7 post so he was comsidered within range.

Now my other vet (yes I have 2) 1 use one for everyday stuff and the other is more state of the art brand new facility I use for Tests.

Now my everyday vets machines scale is this
0-15 Normal
15-25 Possible MVD retest
25+ Possible shunt retest

I asked is a dogs test came in at 15.5 would that be cause for alarm they said NO, they recommend retesting for peace of mind but the 15.5 on either scale is still considerably low being they see reading of 100+ If it was me I would go to lowered protein diet for a month then do another Bile Acid test.
Im no expert but being I thought Diggy was a liver compromised baby I spent MANY hours reading into this and I honestly would not be overly concerned with a 15.5. Can she call the vet and get exact #'s of the scale they use?

Maybe some other YT'ers will have diffrent view on this....and have more options you could explore. This is just what I would do. Hope this helps!
