Patient's question:
The child needs to go to the hospital for a check-up. Could you please explain how neonatal screening is conducted? Can you elaborate on it?Doctor's answer:
Hello. Newborn heel blood tests are mandatory screening items and a means of detecting related congenital diseases. Currently, China mainly screens for congenital hypothyroidism and phenylketonuria. Heel blood is part of peripheral blood, and blood collection is relatively convenient. This has nothing to do with exam results. Generally, exam results will be announced about a month later. If they are abnormal, further tests and a clear diagnosis are required.
