Question : After taking various mgs of Synthroid for a low functioning thyroid FOR THE LAST 50 YEARS,. for the last few months, my thyroid began working on its own. After a blood test on Monday, my PCP ordered a two-day test requiring a radio-active dye to be swallowed. What is the test supposed to reveal? I mentioned to her that it was getting hard for me to swallow.

About thyroid scintiscan

Detailed Answer:

Hello,

Radioactive iodine (thyroid scintiscan) is needed when there are nodules in ultrasound. It is a radiologic examination that determines if the nodule is hot or cold. For cold nodules Citology is suggested after. For hot nodules treatment with radioactive iodine capsules may be an alternative.

Hope the information will help.
