I have new born baby boy of 16 days old I did testing of serum bilirubin test it cam 10 . so it is really worried?

A. In a newborn, higher bilirubin is normal due to the stress of birth. Normal indirect bilirubin would be under 5.2 mg/dL within the first 24 hours of birth. But many newborns have some kind of jaundice and bilirubin levels that rise above 5 mg/dL within the first few days after birth.
