These exams detect virtually all situations of congenital hypothyroidism. Health professionals examine blood amounts of T4, a person of the thyroid hormones, and Thyroid-stimulating hormone (TSH), a material produced by the pituitary gland that tells the thyroid gland to make thyroid hormone. Low levels of T4 and superior amounts of TSH recommend a prognosis of congenital hypothyroidism. Doctors also might do a thyroid scan or an ultrasound examination to glimpse at the dimension and place of the thyroid or to locate out if it is lacking completely.
