Patient's question:
What is the purpose of the newborn heel prick blood test? I just received the results, and one of the indicators is 14.5 (I forgot whether it was PKU or CH, the doctor said the normal value for this indicator is 9).Doctor's answer:
Hello, the heel blood of newborns is used for screening certain congenital diseases (hypothyroidism, phenylketonuria). Suggestions: Normal range of TSH (thyroid-stimulating hormone): 2～10 mU/L Normal range of phenylalanine in serum: 73～212 micromoles per liter
