The following link is from the Linus Pauling Institute:http://lpi.oregonstate.edu/infocenter/minerals/iodine/
Here are snips but read the whole thing. I would hesitate to have any test requiring radioactive iodine before attempting to correct the problem through diet and supplements. Of course any supplements I take would be under a doctor's supervision. Too much iodine is as bad as too little.
"Thyroid enlargement, or goiter, is one of the earliest and most visible signs of iodine deficiency. The thyroid enlarges in response to persistent stimulation by TSH (see Function). In mild iodine deficiency, this adaptative response may be enough to provide the body with sufficient thyroid hormone. However, more severe cases of iodine deficiency result in hypothyroidism. Adequate iodine intake will generally reduce the size of goiters, but the reversibility of the effects of hypothyroidism depends on an individual's stage of development...
Inadequate iodine intake may also result in goiter and hypothyroidism in adults. Although the effects of hypothyroidism are more subtle in the brains of adults than children, research suggests that hypothyroidism results in slower response times and impaired mental function (1). Other symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, and constipation...
Selenium deficiency can exacerbate the effects of iodine deficiency. Iodine is essential for the synthesis of thyroid hormone, but selenium-dependent enzymes (iodothyronine deiodinases) are also required for the conversion of thyroxine (T4) to the biologically active thyroid hormone, triiodothyronine (T3) (6, 8). Additionally, deficiencies of vitamin A or iron may exacerbate the effects of iodine deficiency (6, 14).
