Question

Select the screening procedure performed on newborns to decrease the risk of intellectual disability and compromised neurological development.

Answer 1

That would be serum phenylalanine test.

This test  is a blood test to look for signs of the disease phenylketonuria-PKU (characterized by abnormally high levels of an amino acid phenylalanine). It is done to screen newborns, because if PKU is not detected early, increasing phenylalanine levels will cause intellectual disability.
