Question
How should one diagnose neonatal biliary atresia?
Answer
For pregnant women who suspect their fetus may have biliary atresia, it is important to undergo a series of checks promptly. First, a 4D ultrasound can be used for an initial screening for malformations. In addition, amniocentesis is a common test method, and doctors may recommend this to further determine the fetal liver function status. In some cases, doctors may also suggest taking blood from the umbilical cord of the fetus for testing. Regular prenatal checks are crucial for early detection and diagnosis of neonatal biliary atresia symptoms. Typically, after seven months of pregnancy, an ultrasound can be used to confirm whether the fetus has biliary atresia.
