No they don't, except in very rare cases. Doctors order tests to make a diagnosis. The treatment follows from that.
>If they have absolutely no idea what the possibilities are then they wouldn't be ordering tests anyway.
I'm not sure a doctor would have "no idea what the possibilities are" unless you don't have any symptoms. If you don't have any symptoms, why are you at the doctor's office?

What I said didn't contract what you said. If test => diagnosis => treatment then test => treatment.
