Different vets--even in the same practice--sometimes have different views on things. That's understandable, if sometimes frustrating.
What isn't, in my view, is that you have not been asked about any of this, or been told what has been done. Our discussions on blood work are pretty short these days, because we do the same thing every year. But each and every visit, someone--usually my vet but occasionally another staff member--always goes through the invoice with me.
