    Hi Kalty, have you had any antibody tests done? These are considered to be definitive tests for Graves – it is not guesswork if these tests are positive and they say you’ve got it. There are two tests either of which will work
    1) TSI (thyroid stimulating immunoglobin) this measure the percentage of excess stimulation that is occurring to your thyroid by the antibodies
    2) TRab (thyroid receptor antibodies) this includes a total count of all Graves antibodies which includes stimulating, blocking, and neutral types. For the most part everyone is concerned only about the stimulating antibodies because that’s what drives up the thyroid hormone.

    Normal people have none of these antibodies or very very very low values. Good luck getting your answers!
