This is where I part company with the consensus forming above. 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.

Right, and the exception is worth naming rather than left implied, because the exception is where people get into trouble.

Correct me if the detail matters more than I have assumed.

Found this through search years later and it is still the best discussion of the question, so adding one thing. 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.

Adding the clinical framing, because it changes how the question reads. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

Can confirm. Same sequence, different timescale.
