L pneumophila by urinary antigen testing (LPUAT) is a rapid tool for early diagnosis of Legionella infection (6-14). An enzyme immunoassay (EIA) for detecting L pneumophila serogroup 1, which accounts for between 50% and 70% of cases of Legionella pneumonia (15,16), has been shown to be both sensitive and specific. In addition, some studies have shown that the test is capable of cross-reacting with several L pneumophila serogroups and even other Legionella species (6,9). Specificity is typically more than 99% (7-9).(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2094914/...
