Test ID: BILEA    
Bile Acids, Total, Serum

Method Description Describes how the test is performed and provides a method-specific reference

Testing is performed on the Roche cobas c502. In the presence of Thio-NAD, the enzyme 3-alpha-hydroxysteroid dehydrogenase (3-alpha-HSD) converts bile acids to 3-keto steroids and Thio-NADH. The reaction is reversible and 3-alpha-HSD can convert 3-keto steroids and Thio-NADH to bile acids and Thio-NAD. In the presence of excess NADH, the enzyme cycling occurs efficiently and the rate of formation of Thio-NADH is determined by measuring specific change of absorbance at 405 nm.(Package insert: Diazyme Total Bile Acids Assay Kit, Diazyme Laboratories, Poway, CA. 2010-10)

PDF Report Indicates whether the report includes an additional document with charts, images or other enriched information

No

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Monday through Sunday; Continuously

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

Same day/1 day

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

2 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

1 week

Performing Laboratory Location Indicates the location of the laboratory that performs the test
