Test ID: IGAAB    
Anti-IgA Antibodies, IgG Class, Serum

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

Highly purified polyclonal human IgA coupled covalently to fluorescent microspheres is used as a binder for specific IgG anti-IgA antibodies in serum. After incubating serum with the IgA-coupled microspheres, the microspheres are washed to remove unbound IgG. Fluorochrome-labeled antihuman IgG is added to detect specific IgG antibodies bound during the first incubation. Results are expressed in arbitrary units (U) by comparison to a calibrator known to contain IgG anti-IgA antibodies.(Modified from Rumilla KM, Winters JL, Peterman JM, et al: development and validation of a fluorescent microsphere immunoassay for anti-IgA. Immunohematol 2009;25[1]:24-28)

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.

Tuesday, 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

6 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

Rochester
