I finally seen my lab report and below is the right numbers. I swear my doctors nurse needs glasses. The results of my ultrasound came back but I'm afraid to quote what she said until I see the report myself. She did say there is 2 nodules on the right lobe and 3 on the left. Would these nodules have anything to do with my lab numbers? Thanks for the information.

TSH .20 normal .34 - 5.6
FT4 .77 normal .6 - 1.6
FT3 3.2 normal .2.4 - 4.2

Not very likely.
I read a study once involving 10s of thousands of autopsy studies of thyroid glands. Something like 80-90% of them had nodules of which the deceased weren't even aware. They had no thyroid disease while alive. That's how common asymptomatic nodules are.

Your low TSH is the reason why your FTs are deficient.

I heard if you have a toxic multinodule goiter it will manufacture its own hormones
and will cause low TSH and FT4. Has anyone here had this happen? How does a nodule get to be "toxic"?

Toxic nodules do produce their own hormone, which in addition to that which the gland as a whole produces, causes low TSH and high FT4. The result is hyperthyroidism. That's not what you have.

I'm unsure of the mechanism which causes some nodules to produce excess hormone.
