Legionella pneumophila Antibodies (Types 1-6), IgG, IgM, and IgA by ELISA
Also known as: LEGION AB
Use
This test may aid in the diagnosis of legionellosis caused by infection with L. pneumophila. It detects IgG, IgM, and IgA antibodies to Legionella pneumophila types 1 to 6 using a semi-quantitative enzyme-linked immunosorbent assay (ELISA). The presence of antibodies suggests current or prior infection, but a positive result cannot distinguish between active or previous infections.
Special Instructions
The test requires a serum specimen collected in a serum separator tube (SST) or plain red tube. Ensure the sample is not contaminated or hemolyzed.
Limitations
A positive result cannot distinguish between previous or active infection, and thus cannot be used as a sole basis for diagnosis. Further clinical correlation is required. Icteric, lipemic, contaminated, or heat-inactivated specimens are unacceptable for testing.
