Leave off iron supplement for 7 days (no liver, pate, etc either).

Iron tests should be done after a 12 hour fast (water allowed) so it makes sense to do it first thing in the morning before breakfast.

Fab!

Thanks, Susie. I'm doing my thyroid & iron panel bloods in 10 days or so. I'll do it first thing. 🙂

Sounds like a good plan. Don't forget to leave off your thyroid meds before the thyroid test - last dose of Levo 24 hours before and last dose of T3 or NDT should be 8-12 hours before the test. No B Complex or Biotin for 7 days before the test either. You might know all that but I thought I'd mention it just in case :)

Thank you! I have big reminders in my calendar to stop taking iron and biotin and when to take my levo, since I usually take it in the evening. :)
