Step-by-step explanation:
Most NBS/Newborn Screening tests are ideally performed shortly after birth, within the first 24-48 hours. These tests are important to identify any genetic or metabolic conditions in newborns, allowing early intervention and treatment to prevent long-term health issues. One example of a screening test is the Apgar score, which assesses the newborn's overall wellbeing based on criteria such as skin color, heart rate, reflex, muscle tone, and respiration. The scores are taken at 1 minute and 5 minutes after birth.
