Legionella pneumophila Antibody
Use
This assay can be used to identify exposure to Legionella pneumophila but serological testing is not recommended for diagnosis of Legionella infection. This assay does not differentiate between previous exposure/infection and current infection. Per current recommendations, culture of lower respiratory secretions and/or the Legionella urinary antigen test should be used for diagnosis of infection with Legionella.
Special Instructions
This assay differentiates between previous exposure/infection and current infection. Serological testing is not recommended for diagnosis. Per current recommendations, culture of lower respiratory secretions and/or the Legionella urinary test should be used for diagnosis of infection with Legionella.
Limitations
This assay detects antibodies against L. pneumophila serogroups 1 through 6. It does not detect non-pneumophila, or atypical, Legionella species. This assay cannot differentiate between previous exposure/infection and current infection. A diagnosis should not be made on the basis of Legionella serology results alone; test results should be interpreted in conjunction with clinical evaluation and other diagnostic procedures.
