| Additional information | Legionella pneumophila serogroup 1 antigen can be detected in urine within 2-3 days of infection and may persist even after treatment. Only a small portion of Legionella infections are due to serogroup 1. This assay does not detect other Legionella species or serogroups. Therefore a negative test cannot be used to exclude infection. Regardless of whether a urine antigen test is used, culture of respiratory specimen should always be performed because culture diagnosis continues to be the most sensitive and specific means to diagnose Legionnaire's Disease |
