Just a test: A thyroid uptake and scan is used to aid the differential diagnosis of newly diagnosed thyrotoxicosis and ideally should use i-123 as the radiopharmaceutical (low energy isotope for testing). If the test shows increased thyroid function such as in grave's disease or multi-nodular goiter i-131 can be use to ablate the thyroid gland if this is desire.
