Also known as: radioactive iodine uptake test, RAIU test.
Radioactive iodine imaging is a medical test that helps your pediatrician diagnose how well your child’s thyroid gland functions. It uses a short acting dose of radioactive iodine to determine how much the thyroid can take in over a certain period of time. If the thyroid gland takes in too much or too little iodine, it could be indicative of a medical problem.
No special preparation is needed for this test though, your child may be advised not to eat or take some medications for some hours prior to the test. Patients should tell the doctor if they have diarrhea or have had recent computed tomography (CT) scans or iodine-based tests performed.
The radiation exposure that occurs during this test is fairly small and doesn’t usually cause any problems.
