1 Answer

Answer :

DefinitionRadioactive iodine uptake (RAIU) is a test of thyroid function. It measures how much radioactive iodine is taken up by the thyroid gland in a given time period.See also:Thyroid scanAlternative NamesIodine uptake test; RAIUHow the test is performedYou are asked to swallow a liquid or capsule containing radioactive iodine.After a certain period of time (usually 6 and 24 hours later), you must return to the testing center so that the amount of radioactivity in the thyroid gland can be measured. This is done using a device called a gamma probe.The probe is placed over your thyroid gland along the outside of your neck. You will be asked to lie on a table while the scanner moves over your neck.The scan takes about 30 minutes.How to prepare for the testDo not eat for 8 hours before the
