Thyroid Uptake Study
Your doctor has referred you for a thyroid uptake study that involves the use of a small amount of radioactive material. The level of radioactivity used is extremely low and has no side effects. You can be around other people and use a bathroom normally without risk to others.

Patient Preparation
Diet: You should not eat for 3 hours prior to, or 1 hour after swallowing the capsule. You may drink as much water as you wish.
Medications: Stop all thyroid medications. Thyroid hormone, anti-thyroid drugs, mineral or vitamin supplements containing iodine and recent intravenous contrast from a diagnostic x-ray procedure may interfere with your scan. If you are taking these medications or have had a recent x-ray examination using intravenous contrast, please call ahead and let the technologist know. Your physician will advise you on stopping all thyroid medications.

You will swallow a capsule containing a smalll amount of radioactive iodine and will return in 24 hours time. A measurement of how much of the capsule went to your thyroid will be done on the second visit.

Likely your doctor has also requested a thyroid scan, which will be performed at this time. (Click to see patient information on thyroid scans.)
