Adding the clinical framing, because it changes how the question reads. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

Second this. The detail I would add is minor and it is already implied above.

Moderator note: two posts asking for a source have been merged into one. Please search the thread before asking again.

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.

One thing that is still open after TrialNerd_Beth’s answer:

What would you measure differently if you were starting again?
