Why is screening for pku and hypothyroidism done at birth?

Screening for phenylketonuria (PKU) and hypothyroidism at birth is crucial because early detection allows for timely intervention, preventing severe health issues. PKU can lead to intellectual disabilities if not managed through dietary restrictions, while untreated congenital hypothyroidism can result in developmental delays and growth problems. By identifying these conditions early, healthcare providers can implement treatment strategies that promote healthy development and improve long-term outcomes.
