Evaluation of Two New Immunochromatographic Assays (Rapid U Legionella Antigen Test and SD Bioline Legionella Antigen Test) for Detection of Legionella pneumophila Serogroup 1 Antigen in Urine

摘要

We evaluated two new immunochromatographic assays for their abilities to detect Legionella pneumophila serogroup 1 antigen in urine. The results were compared with those obtained by the Binax NOW urinary antigen test. The sensitivities and specificities were estimated to be 71.2% and 96.6%, respectively, for the Rapid U test; 31.5% and 98.9%, respectively, for the SD Bioline test; and 91.8% and 100%, respectively, for the Binax NOW test.
