What is the main objective of newborn screening?

The main objective of newborn screening is to screen for common abnormalities. This process is critical because it allows for the early detection of certain genetic, metabolic, and endocrine disorders that can affect a newborn's health. By identifying these conditions right after birth, healthcare providers can implement timely interventions that may prevent serious health issues, developmental delays, or even life-threatening circumstances.

Screening typically includes tests for conditions such as phenylketonuria (PKU), congenital hypothyroidism, and sickle cell disease, among others. Early diagnosis and treatment are essential for optimizing the long-term health outcomes of affected infants. The other options, while related to aspects of health, do not directly address the primary purpose of newborn screening, which is focused on immediate health interventions based on screening results rather than tracking growth, assessing family health history, or studying environmental impacts.
