Diagnosis of Iodine Deficiency
Blood tests Presence of a goiter (in adults) Iodine deficiency is diagnosed based on blood tests indicating low levels of thyroid hormones or a high level of thyroid-stimulating hormone (TSH) or based on the presence of a Simple Nontoxic Goiter (only in adults). Doctors do a blood test to check for Hypothyroidism in the Newborn , including that due to iodine deficiency, in all newborns. Imaging tests, such as ultrasonography or thyroid scanning, may be done to measure the thyroid gland and to evaluate any abnormalities.
