Liquid Chromatography Tandem Mass Spectrometry (LC/MS/MS)
Bile acids are elevated in individuals with liver dysfunction, such as hepatitis, cirrhosis, and intrahepatic cholestasis of pregnancy.
Cholic Acid: < or = 5.0 nmol/mL; Chenodoxycholic Acid: < or = 6.0 nmol/mL; Deoxycholic Acid: < or = 6.0 nmol/mL; Ursodeoxycholic Acid: < or = 2.0 nmol/mL; Total Bile Acids: < or = 19.0 nmol/mL.
Do not use for the characterization of peroxisomal biogenesis disorders or inborn errors of metabolism.
