Question

Quizplus · Accepted Answer

The second amniocentesis was performed to monitor the bilirubin concentration, as the first amniocentesis showed a bilirubin level in zone 2 of the Liley graph. This is indicative of possible fetal hemolytic disease, which can cause high levels of bilirubin in the amniotic fluid. Continued monitoring of the bilirubin concentration can help determine if interventions are needed to protect the fetus. The fact that the woman is diabetic and this is her second pregnancy may also be factors in her risk for fetal hemolytic disease, but they are not the reasons specifically for the second amniocentesis. Antibodies would have been detected on the first amniocentesis, so the second one would not be needed for that purpose.
