Evaluation of three immunochromatographic assays for detection of Legionella pneumophila serogroup 1 antigen in urine samples.
The Uni-Gold, the SAS and the Binax NOW immunochromatographic test (ICT) urinary antigen assays for the qualitative detection of Legionella pneumophila serogroup 1 were compared using 39 unfrozen and nonconcentrated urine samples from patients with Legionnaires disease (LD). The Uni-Gold antigen test detected the urinary antigen in 41% (16/39), the SAS antigen test in 61.5% (24/39), and the Binax NOW antigen test in 74.3% (29/39). The Binax NOW ICT assay showed the best results when detecting L. pneumophila urinary antigen.
