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?

Do you have hypothyroid symptoms now? It sounds as though your Thyroid is 'sulking' - ignoring the messages it is being sent by your pituitary. Just a thought - did you have your blood tests at the same time of day each time? Doctors don't seem to recognise that it makes a difference but the TSH changes quite a lot during the day, and is highest first thing in the morning.
I'm symptomless, whether hyper or hypo. I had all my blood tests at different times of the day, sometimes in the morning, sometimes late in the afternoon. Thanks a lot for answer.
