Bile Acids, Fractionated and Total

Laboratory: Quest Diagnostics
Test code: 4668
Specimen: Serum
Fasting: Not stated
LOINC: 14628-2, 30518-5, 30519-3, 30520-1
Turnaround: Set up: Mon-Fri (p.m.); Report available: 4-6 days

Laboratory assay overview

Bile acids are formed in the liver, from cholesterol, stored and concentrated in the gallbladder, and excreted into the intestines in response to food. Elevated concentrations often suggest impaired hepatic clearance due to liver disease. Patients with intestinal malabsorption and metabolic disorders such as Gilbert's disease do not exhibit elevated bile acids concentrations.

Quest Diagnostics population reference ranges

Quest Diagnostics calculates these statistical intervals for this specific assay and demographic group, not as universal optimal targets.

Cholic Acid	≤1.8 umol/L
Deoxycholic Acid	≤2.4 umol/L
Chenodeoxycholic Acid	≤3.1 umol/L
Total Bile Acids	≤6.8 umol/L

Bile Acids, Fractionated and Total, LC/MS-MS

Laboratory: Labcorp
Test code: 503640
Specimen: Serum
Fasting: Not stated
LOINC: 43130-4
Turnaround: 5 - 10 days

Laboratory assay overview

This assay uses LC/MS-MS to quantify the free acid, glycine-conjugate and taurine-conjugate forms of cholic acid, chenodeoxycholic acid, deoxycholic acid, and ursodeoxycholic acid. Bile acids may be measured to investigate obstructive cholestasis in pregnancy.1 In addition, bile acids are required for cholesterol absorption, fat-soluble vitamin absorption, and to provide resistance to overgrowth of intestinal bacteria.1 Bile acid levels may be reduced or elevated due to various genetic defects.

Bile Acids, Fractionated and Total, Pregnancy, LCMSMS

Laboratory: Quest Diagnostics
Test code: 19546
Specimen: Serum
Fasting: Not stated
LOINC: 14628-2, 30518-5, 30519-3, 30520-1
Turnaround: Set up: Mon-Fri (p.m.)

Laboratory assay overview

Intrahepatic cholestasis of pregnancy (ICP) is a rare disorder that typically occurs in the third trimester of pregnancy and is associated with itching, jaundice and disturbances in liver enzymes. While it poses little risk for the mother it may cause problems for the fetus, including preterm delivery, perinatal mortality and other disorders. Measurement of maternal serum bile acids can help in the diagnosis of ICP as the serum total bile acids are increased significantly (6-fold) with large increases primarily in cholic acid (12-fold).

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
