Hello there. I’m aware of the advice on this forum that T4 should be taken 24 hours prior to testing and for T3 instead the 12 hour rule applies.
I am taking a 40mcg Liothyronine capsule right now. Along with 50mcg Synthroid.
When I did my last test I was taking 25mcg Cytomel so I split it into 12.5 x2 that day and took 12.5mcg 12 hours before the test. Firstly, was the T3 result accurate? Secondly, will testing 12hours after 40mcg T3 be accurate or falsely high?
