The Rapid Response™ Legionella Urinary Antigen Test is an in-vitro rapid immunochromatographic assay for the qualitative detection of Legionella pneumophila antigen (L. pneumophila antigen) in urine specimens from patients with symptoms of pneumonia. It is intended to aid in the presumptive diagnosis of Legionella infection (Legionnaires’ disease) caused by L. pneumophila in conjunction with culture and other methods. Outbreaks have occurred repeatedly in buildings such as hotels and hospitals. The Rapid Response™ Legionella Urinary Antigen Test allows for early diagnosis of Legionella pneumophila infection through detection of a specific soluble antigen present in the urine of patients with Legionnaires’ disease. Legionella pneumophila antigen has been detected in urine as early as three days after the onset of symptoms. The test is rapid, giving a result within 15 minutes, and utilizes a urine specimen which is convenient for collection, transport, and subsequent detection of early, as well as later, stages of disease.
