Who is more likely at risk for biliary atresia?

Post Transplant: There are two forms of biliary atresia - congenital (at birth) or acquired. The acquired type most often occurs in the setting of autoimmune disease (though no way to calculate risk) and is one form of chronic rejection of a transplanted liver allograft.

Infants: Infants over the age of 2 weeks who are still jaundiced or getting worse should be worked up for biliary atresia. Yellow tinge to whites of eyes dark urine, big belly, and pale putty colored stools should prompt alarm and get ultrasound of gallbladder and lliver.
