What Is Newborn Screening Tests:

History Of Neonatal Screening:
Newborn screening began in the 1960s under the observation of Robert Guthrie, who also invented a simple blood test that could detect the possible metabolic disorders in the newborn babies. A disorder or defect in the way the body breaks down food or other products (metabolism) PKU (phenylketonuria.) Since then, scientists have developed more tests, to screen newborns for a variety of severe conditions.
The types of newborn screening tests that are done vary from country to country. Most suggest around eight tests while few institutes or childbirth centers recommend more than dozen tests. Screening tests give only preliminary information that tells doctors to do more precise diagnostic tests.

How Is Newborn Screening Done?
The newborn tests are done via two important screening methods:
1. Blood Test:
Blood samples are collected from the baby’s body, primarily the heels. The blood sample is then sent to a lab for a complete analysis.
2. Hearing Test:
This process involves placing a small earpiece or microphone in the infant’s ear that detects the baby’s hearing abilities.
The tests are done when the baby is between 1-7 days old. Mostly these tests are done before the mother and baby are discharged from the hospital.
