Test Catalog

Test Name

Test ID: LEGI    
Legionella Culture

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

Specimens are cultured on buffered charcoal-yeast extract based media (BCYE). Colonies may appear within a few days; however, cultures are incubated for 7 days before issuing a negative report. Positive specimens will be identified via MALDI-TOF MS and/or 16S rRNA gene sequencing.(Edelstein PH: Improved semi-selective medium for isolation of Legionella pneumophila from contaminated clinical and environmental specimens.

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 Sunday; Continuously

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.

7 days

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

10 days

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

2 days

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