FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
Set up: Sun-Fri; Report available: 4-6 days
Reference Range
| 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 |
Clinical Significance
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.
