GGT as a liver health marker — anyone have experience?

The version of this that has an answer is narrower than the version being asked.

There is a second half to this that has not been said yet. Order of operations matters more than any single choice here: establish a baseline, change one thing, wait long enough for it to express itself, then measure again under the same conditions.

The figures, for anyone assembling their own picture. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

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

What would you measure differently if you were starting again?

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. This treats a plausible mechanism as a demonstrated one. Plausible is where you start looking, not where you stop.

That is the short version; the long version is somebody else's post.

That holds where the measurement is reliable. Where it is noisy — and a lot of what gets tracked here is noisy — the same reasoning produces confident nonsense.

That is the short version; the long version is somebody else's post.
