Legionella pneumophila Urinary Antigen
Confirm the diagnosis of Legionella pneumophila serogroup 1 infection
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.
