Question
What does a phenylalanine recheck mean in newborn disease screening?
Answer
The phenylalanine recheck involves testing the levels of phenylalanine, thyroid-stimulating hormone, 17α-hydroxyprogesterone, and glucose-6-phosphate dehydrogenase in a baby’s blood to confirm if the infant has any abnormalities. After collecting the baby’s blood sample, the doctor sends it to the city’s newborn disease screening center for testing.
