Patient's question:
What is the purpose of the newborn heel prick blood test? I just got 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, for newborns, the heel blood test is used to screen for 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
