Clinical Significance
A real-time PCR assay for the in vitro qualitative detection of Legionella spp. in bronchoalveolar lavage, bronchial washes, and tissue specimens. Specimens that test positive on this assay will reflex to culture for confirmation. If confirmed, identification to the species level will be provided, if possible. Nucleic acids from all Legionella species will be detected by this assay. It is unable to differentiate L. pneumophila from the non-pneumophila Legionella spp.
Limit of Detection for Legionella spp. is 400 CFU/mL. Sensitivity is 90.9% and Specificity is 100%.
This test was developed, and its performance characteristics were determined by Banner Health/Laboratory Sciences of Arizona. It has not been cleared or approved by the U.S. Food and drug Administration (FDA). The FDA has determined that such clearance or approval is not necessary since the laboratory is approved under CLIA for high complexity testing.
