Hi Cannoli:
UC Davis Vet School does amino acid analysis and taurine level blood tests:

However, in addition to any tests I would have my dog’s diet evaluated to determine if it was balanced. If the diet is not balanced catching that early on would hopefully avoid any health issues. You can find nutritional evaluation services at some Vet schools.
Here’s a nutrition service that will evaluate raw and home cooked diets:
