This one has a reasonably settled answer, so here it is. The single most useful discipline is bringing the whole panel to a clinician rather than one flagged value. One out-of-range result in isolation generates anxiety and unnecessary tests; the same result next to the trend and the rest of the panel usually generates a shrug.
My prescriber ordered three tests and this board recommends about twenty, and I would like to know which of those two lists is right.
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.
What I am trying to establish is what actually belongs on a baseline panel, as opposed to the enormous list that gets pasted around here.
Practical detail welcome, however dull — the duller the better.

Dr.NutriCornell has the substance of this right. The condition it depends on is worth stating. 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.

Same position here, arrived at the long way round. 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.
Adding the clinical framing, because it changes how the question reads.
PSA: get baseline labs BEFORE starting baseline bloodwork therapy. You need a "before" picture to measure progress. My recommended pre-treatment panel:
- CMP + A1C + fasting insulin
- Complete lipid panel with particle count if possible
- hsCRP, ferritin, B12, vitamin D
- Thyroid panel (TSH + free T4)
- CBC with differential
- Liver panel (ALT, AST, GGT)
- DEXA scan or body composition

Amazing transformation! Starting at 287 lbs, I'm now at 162 lbs after 18 months on semaglutide 2.4mg/wk. These photos show my progress at months 3, 6, 9, 12, 15, and 18. The body recomposition has been incredible — DEXA shows 23% body fat, down from 42%...
