Not sure if this is allowed but have been reading a post on the Facebook group Thyroid Group UK which someone mentions not taking levo before bloods. I have read on here to do just that. This advice was given to a lady who has been hypo for many years but has asked for help in understanding her condition.
Somebody is shooting this advice down stating it is wrong and you can not fool the results like that as the lab will take the dose of levo into consideration. So which is right?
Would like to show some support but am questioning which is right
