Q

Radioactive iodine uptake scans are used to test for:

  1. hyperparathyroidism
  2. hyperthyroidism
  3. hypothyroidism
  4. hypoparathyroidism
A

hyperthyroidism

Radioactive iodine uptake scans (RAIU) test thyroid function by measuring the gland’s ability to concentrate and retain iodine. RAIU is useful to test for hyperthyroidism, because with hyperthyroidism, absorption of iodine is increased and its uptake can be visualized on an image produced by a thyroid scan.
