Risks
The risk is minimal. The amount of radioactivity is very small and there have been no documented side effects. However, as with any radiation exposure, this test is not recommended for women who are pregnant or breastfeeding.
The amount of iodine used is less than a normal dietary iodine intake. A history of iodine (contrast dye) allergy does not necessarily contraindicate testing, although history of allergy to dietary iodine (or shellfish) may contraindicate this test.
