Test ID: SBLAS
Blastomyces Antibody by EIA, Serum
Method Description
Describes how the test is performed and provides a method-specific reference
The Omega Blastomyces Total Antibody EIA assay uses microwells coated with purified Blastomyces yeast-phase antigen. Patient specimen is diluted in diluent buffer and incubated in the coated microwell. If present, IgG and/or IgM antibodies will bind to the antigen. The microwells are washed to remove unbound serum components. A secondary antibody, rabbit anti-human IgG and IgM antibody conjugated to horseradish peroxidase, is added to the microwell and incubated. The secondary antibody will bind to the antibody-anitigen complexes. The microwells are washed to remove unbound conjugate. Substrate solution containing urea peroxide and tetramethylbenzidine is added to the microwells causing a color change. After a final incubation period, stop solution is added to the microwells and the color change is quantified by measuring the optical density (OD). Sample OD readings are compared to calibrator cutoff OD readings to determine results.

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, Sunday; 9 a.m.
