Hi all, hope everyone is well.
Just wanted to know if I should take my thyroxine for the day before my Thyroid function blood tests? Or wait until afterwards? Thanks x

AuntieMandy It depends on what time you take them. There should be 24 hours between your last dose of Levo and blood draw. So if you take your Levo at, say 8am, then take it the day before but on the day of the blood draw take it after your appointment.
