Review:
Radioactive Iodine Uptake Test
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
The radioactive iodine uptake (RAIU) test is a diagnostic procedure used to evaluate the function of the thyroid gland. It measures how much radioactive iodine is absorbed by the thyroid tissue, helping physicians diagnose conditions such as hyperthyroidism, hypothyroidism, and thyroid nodules. The test involves administering a small amount of radioactive iodine orally or through injection, followed by subsequent imaging or measurements to assess iodine uptake.
