Gliadin (Deamidated) Antibody, IgG, Serum
Method Description Describes how the test is performed and provides a method-specific reference
IgG antibodies to deamidated gliadin peptides are detected by enzyme-linked immunosorbent assay by binding to purified peptides adsorbed to the wells of a microtiter plate. Peptides are bound to the wells under conditions that preserve the antigens in their native states. Prediluted controls and diluted patient sera are added to separate wells allowing antibodies to bind to the deamidated gliadin peptides. Unbound sample constituents are washed away and horseradish peroxidase-labeled antihuman IgG antibody conjugate is added to each well. After a second incubation, unbound enzyme-labeled conjugate is washed away and bound conjugate is detected by adding tetramethylbenzidine chromogenic substrate. After a final incubation, colored product is measured spectrophotometrically and the absorbance compared to the low positive calibrator. The intensity of color is directly proportional to the level of IgG antibodies to deamidated gliadin peptides expressed in arbitrary units.(Package insert: QUANTA Lite Gliadin IgG II INOVA Diagnostics, Inc., San Diego, CA)

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; 4 p.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.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
Performing Laboratory Location The location of the laboratory that performs the test
