If newborn disease screening reveals abnormalities, it is recommended to conduct a blood test immediately for reconfirmation. Early detection and treatment can prevent intellectual disability and neural damage. If suspicious symptoms arise, seek medical attention at a regular hospital promptly to avoid delaying the condition and causing irreversible harm to the child’s intelligence and nervous system. Parents should closely monitor their child’s condition and seek timely treatment to avoid severe damage to the child from hereditary metabolic diseases.
