Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

Tests

Check the catalog code, specimen, method and preparation for every test that measures Total Bile Acids. Select up to five tests to compare them side by side.

Quest Diagnostics 3 tests

Single-analyte tests

  • Bile Acids, Total, Pregnancy, Enzymatic 14801

    Serum · Fasting not stated · Turnaround Set up: Daily

    Method and collection
    Method

    Preparation
    ⁠⁠⁠⁠⁠⁠⁠Fast for 8 hours. Note: Fasting does not apply to women with intrahepatic cholestasis of pregnancy, samples should be collected post-prandially.
    Collection
    Centrifuge serum samples within 1 hour of collection and transfer serum into sterile transport tube(s).

Labcorp 2 tests

Single-analyte tests

  • Bile Acids 010330

    Serum · Fasting not stated · Turnaround 2 - 3 days

    Method and collection
    Method
    Enzymatic
    Preparation
    Patient should be fasting; however, a two-hour postprandial level has been used in order to evaluate hepatic function after the gallbladder has been completely emptied (ie, challenge the liver with a high level of bile acids in the portal circulation). For women with intrahepatic cholestasis of pregnancy who need peak bile acid testing, samples may be taken postprandially.
    Collection
    Transfer serum or plasma to a plastic transport tube before freezing. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
    Reference notes
    0.0 – 10.0 µmol/L

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
