Discussions that mention synthroid

Thyroid Disorders board

Hi everyone, I am having my thyroid checked tomorrow and just wanted to know if I should have the bloodwork done on a full or empty stomach? Before or after taking my Synthroid? Does it even matter? What's the best way to get a more accurate result? :confused: Thank you in advance :)
An empty stomach is not required, but don't take the Synthroid until after the test. It can falsely elevate your T4 result.
