How to test for Reverse T3?

[TaraJR]

I'm thinking of getting my RT3 tested. I've just ordered a Medichecks Thyroid UltraVit, but I'd like to check RT3 too.

Are there any recommendations for when you get it done? Eg fasting / not taking Levo or T3 for a certain time beforehand / best time of day?

Thank you!

It will be cheaper to do the Medichecks Ultravit rT3 test at £169 than pay £99 for the Ultravit and another £99 for the rT3 test. That way everything gets done at the same time and you get your rT3:FT3 ratio as well. If you have rT3 done on it's own they can't give you the ratio.

I would contact Medichecks and see if you can change your order.

Don't forget that rT3 test requires a venous blood draw.
