Reference ranges differ between labs, so comparing two reports is close to meaningless.

Is a baseline blood test really necessary before starting something like this?

Same here.

Worth asking what specifically was measured. Pain scores move with mood and function does not. Tolerance was my main issue with ordering in winter too…

A certificate of analysis answers one question and gets quoted as though it answers four.

Half of what people describe as tolerance is a change in the underlying condition, and the two need different answers.
