special scan to see the thyroid gland.
Newborn screening helps to diagnose disorders such as congenital hypothyroidism, G6PD deficiency, congenital adrenal hyperplasia, phenylketonuria and cystic fibrosis. This test is done for the newborns 72 hours after birth (sometimes cord blood is taken). A few drops of blood is taken on a filter paper after a gentle heel prick and sent for the test. It is worth doing it for all the newborns, mainly for early diagnosis of congenital hypothyroidism. This condition, if not treated early may lead to developmental delay and poor IQ in children.
