What is one reason for performing newborn screening tests?

Performing newborn screening tests is primarily aimed at detecting metabolic or genetic disorders early. Early identification of such conditions is crucial because many of these disorders can lead to serious health issues if not treated promptly. By identifying these conditions shortly after birth, healthcare providers can implement early intervention strategies that can significantly improve outcomes and quality of life for affected infants.

For example, congenital conditions like phenylketonuria (PKU) or cystic fibrosis can have severe consequences if left untreated, but with early detection through screening, therapies and dietary modifications can be started immediately to prevent complications. This proactive approach is a key aspect of neonatal care, focusing on prevention and early treatment to enhance long-term health.

In contrast, monitoring weight gain, assessing developmental milestones, and determining blood type serve different specific functions that are not the primary goals of newborn screening tests. While these assessments are important in the overall care of an infant, they do not focus on the early detection of metabolic or genetic disorders like the screening tests do.
