What is the definition or description of: amniocentesis fluid shows bilirubin?

Red blood cells: Bilirubin is a breakdown pigment found in the amniotic fluid when red blood cells are present. These cells could be maternal or fetal. A maternal-fetal medicine specialist can help to figure things out, so ask your OB if a referral is needed.

Component of AF: Bilirubin is naturally found in the amniotic fluid (af). However, with rh sensitization and hemolytic disease of the newborn (hdn), elevated bilirubin levels correlate with the amount of red blood cell destruction. The bilirubin levels can then be used to determine the severity of the disease, need for fetal blood transfusion and aid in timing of delivery.
