This assay detects Legionella pneumophila serogroup one (1) antigen.  A negative test result does not rule out the possibility of Legionella infection due to other serogroups or species of Legionella.  A positive result may indicate a recent or remote infection with serogroup 1. 

A respiratory culture should be considered for outbreak investigational purposes. All positive Legionella isolated should be submitted to the NPHL for molecular sequencing to supplement and epidemiological investigation. 

NUlirt packing list or NPHL Test Order Form (completed in entirety) must accompany the specimen.
