Reference Range for Amniotic Fluid Bile Acids and Bilirubin in Uncomplicated Pregnancies

Reference values for amniotic fluid bile acids and bilirubin at 17-23 weeks in normal pregnancies were established. The significant correlation between bile acids and GGT, combined with the direct biological relevance of bile acids in biliary pathology, suggests potential utility as complementary or alternative biomarkers in pregnancies complicated with non-visualization of the fetal gallbladder.
