The figures, for anyone assembling their own picture. Post reference ranges alongside numbers when you share them. Units differ by country — glucose and lipids especially — and half the confusion in these threads is unit mismatch rather than disagreement.
One thing that is still open after Dr.GutHealth’s answer:
How often to repeat it, because quarterly seems to be the convention and I cannot find the reasoning?

Adding the part of the answer the thread has not reached. Quarterly for the first year is convention rather than evidence, and it is defensible for a simple reason: it is roughly the interval over which HbA1c becomes informative again, since it reflects about three months of glycaemia. After the first year, and once doses are stable, annual is reasonable unless something specific is being followed.
Certified reference materials, analytical reagents, and research-grade standards for peptide verification. Trusted by laboratories worldwide.
Shop Reference StandardsOP back with an update, since a thread like this is useless without one.
Took the whole panel in rather than the one flagged line, and the conversation lasted two minutes instead of generating three more tests.

Agreeing with PeptideChemSF, and the qualification matters more than the agreement. One addition: if the lab changes analytical platform between your draws, the comparison breaks and nobody tells you. It is worth asking when a value moves inexplicably.
