Abstract
We evaluated the ability of a new antigen test TRU Legionella® assay Meridian Bioscience Cincinnati OH USA to detect Legionella pneumophila serogroup 1 antigen in urine The results were compared with those obtained with the Binax NOW® urinary antigen test Binax Portland ME USA The sensitivities and specificities were 73 95 confidence interval CI 65 to 81 and 100 respectively for the Meridian TRU Legionella test and 77 95 CI 68 to 84 and 100 respectively for the Binax NOW urinary antigen test The sensitivity of the Meridian TRU Legionella test increased to 81 if tests were reexamined after 60 min of incubation Prolonged incubation did not affect the specificity We conclude that both assays evaluated have similar performance characteristics and are suitable for the rapid diagnosis of Legionnaires’ disease
