Test Code BAIPD Bile Acids for Peroxisomal Disorders, Serum
Useful For
Biomarker for peroxisomal biogenesis disorders, such as Zellweger spectrum disorder and single enzyme defects of bile acid synthesis, including D-bifunctional protein deficiency and alpha methyl CoA racemases
Monitoring patients receiving bile acid therapy, such as cholic acid, for liver disease due to peroxisomal biogenesis disorders or single enzyme defects in bile acid synthesis
Method Name
Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS)

Reference Values
Dihydroxycholestanoic acid: ≤0.10 nmol/mL
Trihydroxycholestanoic acid: ≤1.30 nmol/mL
Total cholic acid: ≤5.00 nmol/mL
Total chenodeoxycholic acid: ≤6.00 nmol/mL
Total ursodeoxycholic acid: ≤2.00 nmol/mL
Total bile acids: ≤19.00 nmol/mL
Interpretation
Increases in serum C27 bile acids are seen in patients with peroxisomal biogenesis disorders (eg, Zellweger spectrum disorder) or single enzyme defects of bile acid synthesis (eg, D-bifunctional protein deficiency and alpha methyl CoA racemaces). Total bile acids are metabolized in the liver and can serve as a marker for normal liver function. The values of 2 bile acid precursors, dihydroxycholestanoic acid and trihydroxycholestanoic acid, will be reported, along with total cholic acid, total chenodeoxycholic acid, total ursodeoxycholic acid, and total bile acids. No interpretive report will be provided.
