Your child’s healthcare provider makes a tiny cut in the baby’s heel to get a small amount of blood to test. Well infants are usually tested just before they go home from the hospital, but not later than 72 hours after birth. Sick or premature infants are tested at 1 week of age, or earlier if a screenable disease is suspected. If a test suggests your child has a disease, the health department will contact you and your baby’s doctor. If the tests do not show any diseases, you will generally not be contacted. Your baby’s doctor usually has copies of the newborn screening test results. If your baby needs a blood transfusion, blood tests should be done before the transfusion. Some states provide a second set of newborn screening tests between 1 and 2 weeks of age. This is important if the newborn leaves the hospital less than 24 hours after birth. Parents may refuse to have their newborn screened because of religious beliefs or personal beliefs. Parents who refuse to have the testing done

For this test, a drop of food extract is put on the skin and then the skin is pricked with a small needle through the drop of the food extract. The test can also be done with a pricking device that has been presoaked in the food extract. Only the top layer of skin is pricked. The test is usually done on the back or the arm. The skin test is ready to check in about 15 minutes. If you are allergic to the food in the extract, a red bump that looks like a mosquito bite will appear at the spot where the food extract was placed.

The health care provider responsible for the infant’s care receives the results. Hearing loss tests measure how a baby responds to sounds. The tests use either a tiny, soft earphone or microphone that is placed in the baby’s ear.
