Question
What are TSH and PKU in newborn disease screening?
Answer
TSH and PKU are common indicators used in newborn disease screening to check for congenital hypothyroidism (thyroid-stimulating hormone, TSH) or phenylketonuria (PKU). Hypothyroidism can lead to growth delays and impaired intellectual development, while PKU is a genetic disorder where patients cannot metabolize certain amino acids, requiring special dietary control. A normal screening result indicates that the child does not have these congenital diseases.
