Confirm the diagnosis of Legionella pneumophila serogroup 1 infection
This test will not detect species or serogroups other than Legionella pneumophila serogroup 1.
Enzyme immunoassay (EIA)
No Legionella pneumophila serogroup 1 antigen detected
Legionella pneumophila has been estimated to cause 80% to 85% of Legionella infections, with serogroup 1 accounting for most of these. Current methods of diagnosis for Legionella infection include culture and DFA. All of these other tests require a high quality respiratory specimen to perform this test and, unfortunately, many patients with Legionella infection do not produce sputum. A number of investigators have shown that a specific soluble antigen was present in the urine of patients with Legionnaires' disease, which can be detected both early and late in the disease.
Causes for Rejection
Swab specimen; inappropriate specimen transport device; unlabeled specimen or name discrepancy between specimen and request label; nonurine specimen
