What is this new medication Thyrogen? And how does it help with the performance of tests to find recurrent thyroid cancer?
Thyrogen is genetically engineered human TSH, exactly like what your own pituitary gland makes. Injections of Thyrogen (in your buttock) stimulate remaining thyroid tissue to make Tg and take up radioiodine. And it does it without stopping thyroxine medication and all of the symptoms of hypothyroidism that this causes.
