Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).
Obviously you need TSH, Ft4 and Ft3 tested together
Possibly cheapest option for getting all tested via DIY finger prick test
TSH, FT4 and FT3
