Diagnosis of Simple Nontoxic Goiter
Thyroidal radioactive iodine uptake Thyroid scan Thyroid ultrasonography Thyroxine (T4), triiodothyronine (T3), and thyroid-stimulating hormone (TSH) levels In the early stages, thyroidal radioactive iodine uptake may be normal or high with normal thyroid scans. Laboratory Testing of Thyroid Function results are usually normal.
