I got a full panel before starting and a repeat at three months, and the second one is more useful than the first purely because I now have something to compare against.

What would genuinely help is knowing how often to repeat it, because quarterly seems to be the convention and I cannot find the reasoning.

Not looking for reassurance. Looking for the part I have got wrong.

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

No disagreement with Dr.GastroMayo. One condition attached. 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.

From the other side of the consultation, briefly.

Blood work came back perfect. baseline bloodwork + this community = winning. 🏆
