“never take your thyroid hormones before that that's less applicable to people on t4 only but if you're taking anything with t3 in it it's going to peak and dissipate within a certain period of time you're going to get a false test that's going to be not like oh things look good it's because you just swallowed that stuff in two hours then you got the blood draw we want to see free t3 what's free and unbound and available not what you just sent coursing through your veins because you swallowed it so never let a doctor tell you to take your thyroid hormones before a test”
