Diagnosis of Simple Nontoxic Goiter
Thyroid function tests Ultrasonography and a thyroid scan Doctors usually do blood tests to determine how the gland is functioning ( Thyroid function tests ). They measure blood levels of the thyroid hormones thyroxine (T4, or tetraiodothyronine) and Doctors do a radioactive iodine uptake test and a Thyroid ultrasound . For these tests, the person ingests (or is injected with) a small amount of radioactive iodine. The radioactive iodine concentrates in the thyroid gland. A scanner can detect how much iodine is taken up by the gland and a gamma camera (which detects radiation) produces a picture of the thyroid gland. These scans show any physical abnormalities in the gland that might suggest Doctors do ultrasonography, which uses sound waves to create an image of the thyroid gland, to identify any nodules that could be cancerous.
