IGF-1 levels on GLP-1 — March 2026

Dr.RenalNash said:

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…

I read this differently from Dr.RenalNash, on substance rather than tone. I would drop the "get everything" instinct further than this thread does. Every extra test is another chance at a false positive, and incidental findings have their own cost in scans, biopsies and worry.

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

Shot day Monday report relevant to baseline bloodwork:

Week 31. Currently on 1.0mg. Down 47 lbs from starting weight of 259 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.

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

Following on from WendyG_ATL — and this may be the naive question:

How often to repeat it, because quarterly seems to be the convention and I cannot find the reasoning?

Reporting back.

Took the whole panel in rather than the one flagged line, and the conversation lasted two minutes instead of generating three more tests.
