ATTI - Performance: Antithrombin Antigen, Plasma

Test Catalog

Test ID: ATTI    
Antithrombin Antigen, Plasma

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

This assay is performed on the Instrumentation Laboratory ACL TOP using the Diagnostica Stago LIATEST AT III kit. Antithrombin antigen is determined using automated latex immunoassay (LIA) methodology. Patient plasma, containing antithrombin antigen, is combined with a latex reagent containing rabbit antihuman antibodies. An antigen-antibody reaction takes place, causing the latex particles to agglutinate and form aggregates. The aggregates form diameters greater than the wavelength of the light (405 nm) passing through causing absorption of the light. This change in absorption is measured over time and reported as delta optical density. The increase in absorption is proportional to the concentration of antithrombin antigen present in the sample.(Package insert: LIATEST AT III.

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

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.

2 hours

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

4 days

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

7 days

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