I won't subject my dogs to a test where there is no indication that it is needed. If the ALT levels came back elevated, there was a history of it in my line, or one of my dogs threw a pup that was diagnosed with LS than there would be a need. I would guess that most responcible breeders do a blood panel and than would proceed from there if there is any indication that more testing is needed.
