In the developed world, nearly all cases of<unk>  are detected by the newborn screening program. These are based on measurement of TSH or thyroxine (T4) on the second or third day of life (Heel prick). Evaluation If the TSH is high, or the T4 low, the infant's doctor and parents are called and a referral to a pediatric endocrinologist is recommended to confirm the diagnosis and initiate treatment. A technetium (Tc-99m pertechnetate) thyroid scan detects a structurally abnormal gland, while a radioactive iodine (RAIU) exam identifies congenital absence or a defect in organification (a process necessary to make thyroid hormone).
