A narrower follow-up, since the general answer is now clear:

Did your prescriber agree with that reading, and if not what was their objection?

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

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The counter-case has not been addressed. Somebody upthread described the situation that does not fit, and the thread moved on rather than engaging with it, which is the failure mode this board is supposed to avoid.

Ask again with the specifics and you will get a better answer than this one.

That is right for the common case. Whether it is right for the case being asked about depends on a detail that has not been given.

This is exactly what I could not find anywhere else. Printing the relevant bit and taking it with me.

OP back with an update, since a thread like this is useless without one.

Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
