International vendor directory — need advice

Following on from Dr.NutriCornell — and this may be the naive question:

What would you measure differently if you were starting again?

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. 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.

Worth separating that from vendor vetting, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

That reframing is the part I needed.

Clinical perspective, offered as context rather than as advice. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.
