Thyroid Uptake and Scan
A thyroid uptake and scan is a test that uses a radioactive substance and a scanning tool to evaluate the thyroid gland. The scanner picks up where and how much the radioactive substance was taken up by the thyroid. This helps determine the structure, location, size, and activity of the gland.
The scan may be ordered to:
- Determine the cause of an overactive thyroid (hyperthyroidism)
- Test how well the thyroid is working
- Determine if a thyroid nodule is functioning (if it is making thyroid hormone)
