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
