Thank you for posting query.
presentation of High T4 with Low
TSH. (Graves disease diagnosis mentioned without anti bodies status)
Firstly, a low TSH indicates "primary Hyperthyroidism". It is very UNLIKELY now that a pituitary
tumor is there. "Pituitary tumor maybe ruled out".
antibodies result would give a clear picture of your current presentation.
and/OR you may need consider another treatment option.
now , in your case, if you have a clear diagnosis of Graves disease, you maybe take an advice from your treating physician for a
'Radioiodine therapy".
hope to answer your concern.
any further queries are welcomed.
Health professionals aim to diagnose properly and manage patients according to their limited knowledge. Cure is blessed by the ONE who Created us, whose power and knowledge is unlimited .
wish you good health.
regards,
Dr Tayyab Malik
