Is it possible to still have iodine defeciency even if your thyroid t3, t4, & tsh are all in good levels? if so, how do you test for it?

Yes: A "TOTAL IODINE" is a common study often done in cases of suspected Iodine deficient thyroid problems..early deficiency does not effect thryoid function. Iodine deficiency is quite RARE since use of Iodine supplements in Table Salt! Hope this is helpful' BE WELL! Dr z

Agree with Dr. Z.: If you are taking iodized table salt, it is unlikely that you have iodine deficiency. Have a healthy diet, exercise, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine
