Either way is fine. There are some questions about the Protein C test right now, so I'd personally redo the bile acids instead. It's very possibly a problem common in Yorkies and may not turn out to be anything serious.
The increased drinking doesn't sound right though. I'd say if it was right when he got home, it could have been the food they gave him, but it does sound odd. A few things come to mind. If it continues, a vet should be willing to figure out what is causing it. The yellow bile he just threw up, did he eat before you went to bed or does he have an empty stomach?
