IGGS - Performance: IgG Subclasses, Serum

Test Catalog

Test Name

Test ID: IGGS    
IgG Subclasses, Serum

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

The concentrations of immunoglobulin G (IgG) subclass proteins in serum are measured by automated nephelometry in which the concentrations of each protein are determined from standard curves. The intensity of light scattered by immune complexes of IgG-subclass proteins and specific reagent antibodies is compared to standard curves plotted from the reactions of protein standards with the same reagent antibodies.(Instruction manual: Siemens Nephelometer II.

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 Saturday; Continuous

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

2 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
