Answering the narrow version, because the broad one does not have a single answer. 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.

Ask again with the specifics and you will get a better answer than this one.

Agreeing with TrialNerd_Beth, 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.

My prescriber ordered three tests and this board recommends about twenty, and I would like to know which of those two lists is right.

This matches mine closely enough to be worth saying so. A defensible baseline is short: HbA1c and fasting glucose, a lipid panel with ApoB if you can get it, ALT and AST, creatinine with eGFR, TSH, ferritin and B12, and a full blood count. That set catches the things that change, the things that explain symptoms, and the things that alter the prescribing decision. Almost everything else on the long circulating lists is either invariant, uninterpretable without a specific question, or an incidental finding waiting to cause an unnecessary workup.

Clinical perspective, offered as context rather than as advice.

Shot day Monday report relevant to baseline bloodwork:

Week 35. Currently on 1.0mg. Down 61 lbs from starting weight of 273 lbs.

This week's observations: Appetite very well controlled, no cravings.

Labs due next week — looking forward to seeing the metabolic panel. I'll post results in the Lab Results section when they come in.
