Jasper97,

High TSH with FT4 and FT3 in range while taking 100mcg Levothyroxine means you are under medicated. It will be unrelated to the adrenal tumour. If you post your thyroid results and ranges members will advise.

T3 .08 T4 7.0 TSH 16.64

Jasper97,

I can't see whether T4 and T3 are in range but TSH 16.64 is too high and you need dose increases until it comes down to around 1.0. Increases are usually in 25mcg increments every 6-8 weeks.

T-3 RANGE 0.7-1.7 ng/mL-----.08

T-4 RANGE 4.0-11.0 ug/dL---7.0

TSH RANGE .50-6.00 uINU/mL

Will higher dose effect the T-3/T-4 numbers??

Jasper97,

Increasing dose will raise T3 and T4 levels which will then reduce TSH level.
