Old thread, but it comes up first when you search for this, so it is worth updating. Say what you would expect to see if you were wrong, before you look. It is a small discipline and it changes what you notice.

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

Worth stating the units and the reference range whenever you post a number here.

That is right, and it stops being right at the edges. The general case is well behaved; the interesting cases in this thread are all at the boundary where the general case breaks.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. Printing the relevant bit and taking it with me.

Closing the loop on my own question.

Reporting back for the archive rather than for the thread: I did the narrow version of what was suggested, gave it the full interval, and it settled. Posting it because threads without a follow-up are half a thread.

Same pattern here, and in the same order.
