I guess my question would be, are you sure your vet knows how to do a bile acids test properly? If she is asymptomatic and Tufts got a normal reading, I would have to question the vet with the odd numbers. Idexx itself is fine. Paired samples around a meal are fine but all the pres and posts should make sense when compared.

Honestly, I would go to another vet entirely, have them do a bile acids test sent to Idexx and go with their results. You could just be safe and do the scintography but that is pricey...
