That holds where the measurement is reliable. Where it is noisy — and a lot of what gets tracked here is noisy — the same reasoning produces confident nonsense.

I would rather be corrected than agreed with, if it comes to it.

This answered a question I did not know how to ask. Sending this to two other people who asked me the same thing last week.

Pushing back on PharmD_Rodriguez here. Pushing back on the consensus forming here. Consistency is not the same as correctness, and a board that agrees with itself quickly is usually agreeing with the first person who sounded certain.

The figures, for anyone assembling their own picture. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Moderator note: reminder that nothing in this thread is medical advice, and that clinical claims need a source. Report rather than reply if it drifts again.
