Thyroid test query

[VEG71]

Morning all

I'm going for my thyroid test soon, when should I stop taking my vitamins & supplements?

Many thanks

Vicki

Stop levo 24 hours before the blood test (which is ideally done fasting); lio between 8 and 12 hours before; and any supplements with biotin a week before (possibly too late to tell you now!)

If testing iron and ferritin levels stop iron supplements a week before test and make sure it’s a fasting test
