>Doctors order tests to help them choose the right treatments.

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.

Without a diagnosis, how could a doctor possibly know the answer to the question "what happens if we do nothing"?

I never said without a diagnosis.

It's pretty rare to arrive at a diagnosis without tests.
