A nurse is discussing newborn metabolic screening with parents who state, "Our baby looks perfectly healthy. Why does she need this?" What is the best response?

Some genetic disorders are not visible at birth but can cause serious problems if untreated.

This is to test the newborn's jaundice level at 24 hours of life so we can treat hyperbilirubinemia if your newborn develops it.

The metabolic screening is primarily used for state research purposes and is voluntary.

The test ensures your baby's immune system is developing normally.
