The heel blood sampling for newborns is generally conducted three days after birth, and the results are usually available within ten days to half a month. If there are any abnormalities detected by the screening center, the family will be notified by phone for further examination. If there are no issues, parents can check the results online or inquire at the laboratory of the screening hospital one month after birth by referring to the website provided on the screening card.

The heel blood sampling for newborns is primarily used for newborn disease screening. Through screening for phenylketonuria and thyroid function tests, it can help detect congenital genetic diseases in newborns early on and facilitate timely treatment to promote their healthy growth. Although some congenital metabolic diseases have a low incidence rate, they can seriously affect intellectual development and lead to lifelong disability. Since these diseases cannot be diagnosed before birth and often show no symptoms in the early stages after birth, neurological damage can be irreversible and treatment opportunities can be lost once abnormalities arise. Therefore, early screening, early detection, and early treatment after birth can help prevent harm and intellectual disabilities in affected infants.

So, what is the purpose of the heel blood sampling for newborns? Firstly, it is a free screening program in China, aiming to detect congenital hypothyroidism and phenylketonuria. Both of these diseases can pose significant risks to the nervous system of infants if not properly managed. Secondly, the heel blood screening for newborns is a rigorous process that often requires large hospitals to conduct. Therefore, the time required for results may vary depending on the location. Typically, it takes around one to two months from the time of testing to receiving the results. However, hospitals will notify parents through appropriate channels, so there is no need for undue concern.
