Test ID: SLEG    
Legionella pneumophila (Legionnaires Disease), Antibody, Serum

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

The Legionella kit is designed to detect IgG/A/M class antibodies to Legionella pneumophila in human sera. The test procedure involves 3 incubation steps:

1. Test sera (properly diluted) are incubated in multiwells coated with an inactivated, solubilized cocktail of Legionella pneumophila groups 1-6 bacteria (antigen). Legionella specific IgG, IgM, or IgA antibodies in the specimen will bind to the immobilized antigen. The plate is washed to remove unbound antibody and other serum components.

2. Peroxidase conjugated goat antihuman IgG/A/M is added to the wells and the plate is incubated. The conjugate will react with antibody immobilized on the solid phase in step 1. The wells are washed to remove unreacted conjugate.

3. The multiwells containing immobilized peroxidase conjugate are incubated with peroxidase substrate solution. Hydrolysis of the substrate by peroxidase produces a color change. After a period of time, the reaction is stopped and the color intensity of the solution is measured photometrically. The color intensity of the solution depends upon the antibody concentration in the test specimen.(Package insert: Legionella IgG, A, M ELISA II, Wampole Laboratories, Princeton, NJ 2005-016-16)

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, Wednesday, Friday; 2 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

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

4 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
