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…

This is where I part company with the consensus forming above. 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.

Correct me if the detail matters more than I have assumed.

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 Wednesday report relevant to baseline bloodwork:

Week 17. Currently on 5mg. Down 43 lbs from starting weight of 255 lbs.

This week's observations: Mild fatigue day 1-2 post-injection, then fine.

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

PSA: get baseline labs BEFORE starting baseline bloodwork therapy. You need a "before" picture to measure progress. My recommended pre-treatment panel:

  1. CMP + A1C + fasting insulin
  2. Complete lipid panel with particle count if possible
  3. hsCRP, ferritin, B12, vitamin D
  4. Thyroid panel (TSH + free T4)
  5. CBC with differential
  6. Liver panel (ALT, AST, GGT)
  7. DEXA scan or body composition

Total cost at Quest without insurance: ~$200. Worth every penny for the data.

One thing that is still open after lisa_labSD’s answer:

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

OP 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.
