Hacker news is a community of (from what I've seen) strong critical thinkers, with a poster in a thread often having a specific background in the field being discussed. Doctors aren't mythical beings, and discourse here about what medical tests are 'worth it' seems both appropriate and really interesting.

If I met a community of strong critical thinkers about Chemistry or Civic Engineering I wouldn't ask them advice for my software stack.
Besides, with the exception of a 20% or less who knows what they're talking about (and those only for narrow Computer Science or Engineering fields each), the others might as well be on Reddit. You can find tons of uninformed opinion about anything here. Plus a huge tendency to go with the latest fads (Rails, then JS, then Go, then Rust, etc).
Oh come on... outside of a few notable individuals, nobody really knows who anybody here is, or what their credentials are to talk about anything.
Law and Medicine are two of the things most likely to precipitate a lot of online commentary by people who don't have the first clue of what they're talking about.
