Do I take T3 as normal before blood tests?

[cazzaleo]

Hi all

I started on T3 just over a month ago. I’ve told my endo that I feel there is a very small benefit from it and I would like to increase the dose if possible. He has said he needs me to have more blood tests first to check my TSH, T4 and T3 and I’m having the blood taken Tuesday.

My question is - should I take the T3 as normal or do I need to do something different?

I’m currently taking 10mcg at about 7.

Many thanks in advance!

You need to leave a gap of 12 hours between your last dose of T3 and the blood draw - 24 hours for T4 (levo). Otherwise, you will just be testing the dose you just took, and will get a false high. Not good if you want an increase!

Thank you greygoose!

My endo didn’t say anything about what I should or shouldn’t do, and it didn’t occur to me til later that maybe I shouldn’t take it as usual.

I really appreciate your help 😃

I doubt your endo even knows!
