Test ID: C2729    
Breast Carcinoma-Associated Antigen (CA 27.29), Serum

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

This is a chemiluminometric immunoassay. The instrument used is a Siemens Advia Centaur. The signal (Lite) reagent is a monoclonal antibody specific for CA 27.29, which is labeled with acridinium ester. Purified CA 27.29 antigen attached to paramagnetic particles (solid phase) competes with the antigen in the specimen for binding to the monoclonal antibody. An inverse relationship exists between the amount of CA 27.29 in the patient sample and the amount of relative light units (RLUS) detected by the system.(Package insert: Advia Centaur CA 27.29. Siemens, East Walpole, MA, February 2002)

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 Friday; 3rd shift

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 Medical Laboratories until the release of the test result

3 days

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

30 days

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

New England
