Newborn Screening: What Tests Are Done and Why They Matter?
Newborn screening is a set of simple, quick tests performed shortly after birth to check for serious but rare conditions that aren't visible at first glance. Many of these conditions — metabolic, hormonal, hearing-related, or heart-related — don't show obvious symptoms in the first days of life, but can cause serious health problems if left undetected. Catching them early allows treatment to begin before any real damage occurs, which is exactly why every baby, healthy-looking or not, is screened.
