Iodine uptake test

An iodine uptake test measures how well your thyroid gland absorbs iodine from your bloodstream. Since the thyroid needs iodine to produce hormones, this test evaluates its function. During the test, you drink a small amount of radioactive iodine or take a capsule. After a few hours, a special scanner measures how much iodine your thyroid has absorbed. This helps doctors determine if your thyroid is overactive, underactive, or functioning normally, aiding in accurate diagnosis and appropriate treatment planning. The test is safe, minimally invasive, and provides important information about thyroid health.
