I was diagnosed with an over-active thyroid in September 2012 - maybe Graves but I went private after being letting down by the NHS and my private endo is not sure I have Graves.
Anyway, after one month of 15mg of Carbimazole, my T4 went down from 34 to 15 (9-19) with TSH suppressed. My TSH came back after 2 months and went up to 2.4 with Carbimazole but my T4 always remained at 15. I've been off Carbi for 6 months now, my TSH is low 0.6 (0.4-5) but my T4 are still at 15.
My endo has no explanations and find this strange. I have a new blood test to do: TSH receptor antibodies, thyroglobulin and thyroid peroxidase.
Did someone experience the same or have an explanation for this strange behavior?
