Done within few hours after birth, these are fundamental for early detection of a series of diseases:

Heel-stick test

Usually done about 48 hours after birth, after the baby has been properly breastfed. A small amount of blood is taken from the newborn’s heel, which doctors can screen for a myriad of diseases, such as congenital hypothyroidism and diseases that can cause mental deficiencies.

Newborn hearing test

It’s done through a machine that emits sound waves into the baby’s ear and analyzes the newborn’s response to the stimuli. In some cases, there might still be some liquid inside the child’s ear, in which case the test has to be repeated.

Vision test for babies

Know how a red reflex shows up on someone’s eye when taking pictures with the flash on? That’s a sign that the light has reached the retina, traveling through all the structures of the eye, and reflecting back. This test, while difficult to perform on such small babies, is essential for early detection of diseases that can compromise the vision, such as congenital glaucoma.
