I completely agree with you. I'm pretty picky about what tests I'll take for exactly that reason: stress is dangerous to one's health and many tests have abysmal false-positive rates. My hypothesis is that people, on balance, would be healthier if they took a more active role in their healthcare. I've seen it in a lot of people's lives, but there is a strong confirmation bias there. You don't see the people that tried and wound up worse off. Fortunately, this is easy to study. We could find an answer to whether people are better off, and, more importantly, how to ensure they are better off.
