Evaluation of a new rapid test for detection of Legionella pneumophila serogroup 1 antigen in urine

摘要

For the diagnosis of legionellosis, a new rapid immunochromatographic test (V-tesT CORIS BioConcept) for detection of Legionella pneumophila serogroup 1 antigen in urine was evaluated in 21 samples of patients with legionellosis and 45 samples from patients with other respiratory infections. Results were compared with those obtained by a commercially reference test (BinaxNOW Legionella - Binax).The overall sensitivity was 90.4% for both tests; concordance was 100%; specificity was 100% as well. In conclusion, the V-tesT CORIS seems to be a prompt and suitable diagnostic tool in legionellosis diagnosis.
