> As the customer in such a circumstance are you within your rights to refuse any such diagnosis tests when you reasonably believe they are unnecessary?

Of course. You're within your rights to refuse any medical test or procedure whatsoever, including one that would save you from imminent death, unless you're first declared mentally incompetent, which is not a quick or simple process.

But most people will trust the doctor when he says "we need this test to treat you effectively." He's the expert, and I don't want to bet my health on the possibility that he might be scamming me.

And docs honestly believe that the test will help. Many are not scamming you, they really want to know the result.

The single most helpful question I have if you're deciding on whether to take or refuse a test is this: "How will knowing the result change the course of treatment?" I avoided an intestinal biopsy once this way, as the answer was, "It won't. It would just be nice to know."

Thanks, that is a good question to ask. I'll have to remember that.
