Test ID: BP    
Bullous Pemphigoid, BP180 and BP230, IgG Antibodies, Serum

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

This enzyme-linked immunosorbent assay (ELISA) method detects and measures serum levels of antibodies of certain pemphigoid diseases. Calibrators and patient sera are added to microwells coated with bullous pemphigoid (BP) BP180 and BP230 antigens, allowing antibodies to react with the immobilized antigens. After washing to remove any unbound serum proteins, horseradish peroxidase-conjugated IgG is added and incubated. Following another wash step, the peroxidase substrate is added and allowed to incubate for an additional period. Stop solution is then added to each well to cancel the enzyme reaction and to stabilize the color development. The assay can be quantified by measuring the reaction photometrically and plotting the results.(Unpublished Mayo method)

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; 7 a.m.-5 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.

Same day/1 day (Samples are tested 1 day/week)

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

5 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

14 days

Performing Laboratory Location The location of the laboratory that performs the test

Rochester
