The mechanism and the magnitude are separate questions.

Same pattern here, and in the same order. Nothing to add that would improve it.

One practical note: write down what you did and when, before you need it.

This matches mine closely enough to be worth saying so out loud. Posting only so the count is not one.

Adding the part of the answer the thread has not reached. 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.

One concrete data point for the thread. 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.

Happy to go further on any of that.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful.
