Thyroid Scan Uptake RAIU
Measures how much radioactive iodine the thyroid absorbs to check gland activity and causes of abnormal thyroid function.
What is a Thyroid Scan Uptake RAIU Test?
A Thyroid Scan Uptake (RAIU) measures how much radioactive iodine the thyroid gland absorbs. This tells doctors how active the thyroid tissue is. Thyroid activity is important because thyroid hormones control metabolism, heart rate, temperature, and energy. The test helps detect causes of an overactive or underactive thyroid. It can identify Graves disease, toxic nodules, or thyroiditis. Doctors use the scan to distinguish different thyroid problems and to plan treatment. Results help decide whether medicines, radioactive therapy, or surgery may be needed. The scan is often used with blood thyroid tests for a complete picture.
Thyroid Scan Uptake RAIU Test Preparation
Avoid iodine medications/contrast for 4–6 weeks; follow your doctor's instructions.
Thyroid Scan Uptake RAIU Test Parameters
The Thyroid Scan Uptake RAIU test evaluates various parameters related to the different components. Here are the main parameters that are checked in the test:
Why Take a Thyroid Scan Uptake RAIU Test?
Thyroid Scan Uptake RAIU is usually ordered as part of a thyroid function evaluation when blood tests suggest abnormal thyroid activity. Your doctor may request it for symptoms like unexplained weight change, rapid heartbeat, heat intolerance, fatigue, or a swollen neck. It helps diagnose causes such as Graves disease, toxic nodules, or thyroiditis. Abnormal results can come from medications, recent iodine exposure, autoimmune disease, or nodules. A family history of thyroid disease may make this test more important.
