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

The ST2 assay is an FDA 510K-cleared in vitro diagnostic device. It is a quantitative 2-site manual enzyme-linked immunosorbent assay (ELISA) validated for use in human sera. The capture monoclonal antibody (mouse antihuman ST2) is immobilized on 96-well plates, while the second mouse monoclonal antihuman capture antibody functions as the tracer antibody for detecting ST2, which is bound to the capture antibody. The tracer antibody is biotinylated and bound with streptavidin-horseradish peroxidase during incubation and detection occurs following addition of tetramethylbenzidine substrate.(Package insert: Presage ST2 Assay, Critical Diagnostics Inc., San Diego, CA, July 2014)

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; 8 a.m.

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.

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

14 days

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