What does it mean when a child's initial tandem screening result is negative?

Under normal circumstances, a negative initial screening result in children indicates good health. The detailed explanation is as follows:

The initial screening for infants is typically used to detect the presence of congenital phenylketonuria (PKU). Congenital PKU mainly presents clinically with delayed growth and development, slow intellectual development, dry skin and hair, among other symptoms. A negative test result indicates that the child does not have this metabolic disorder, which is considered normal. Children should regularly consume adequate protein, vitamins, and other essential nutrients, and engage in appropriate physical exercise to strengthen their immune system, resist external disturbances, and grow up healthily. Regular monitoring of newborns' physiological conditions can also help identify and eliminate potential health risks early. A negative screening result is normal, and parents should provide their children with a balanced diet and timely supplementation of various necessary nutrients.

If a child develops any symptoms of illness, it is recommended to seek medical attention promptly to avoid delaying treatment.
