Comparison of diagnostic sensitivities of three assays (Bartels enzyme immunoassay [EIA], Biotest EIA, and Binax NOW immunochromatographic test) for detection of Legionella pneumophila serogroup 1 antigen in urine.

چکیده
The Bartels enzyme immunoassay (EIA), Biotest EIA, and Binax NOW immunochromatographic test (ICT) urinary antigen kits for the detection of Legionella pneumophila serogroup 1 were compared using 178 frozen urine samples. When nonconcentrated urine samples were used, the sensitivity levels of both enzyme EIAs were significantly higher than the sensitivity level of the ICT (Bartels EIA, 71.3%; Biotest EIA, 65.1%; Binax NOW ICT, 37% [P < 0.001]). After concentration of the urine samples, no significant differences in sensitivity were found among the three tests.

Evaluation of the Oxoid Xpect Legionella test kit for detection of Legionella pneumophila serogroup 1 antigen in urine.
We evaluated a new immunochromatographic assay (Oxoid Xpect Legionella test kit) for the ability to detect Legionella pneumophila serogroup 1 antigen in urine. The results were compared with those obtained with the Binax NOW urinary antigen test by following the manufacturers' instructions. The sensitivities and specificities were estimated to be 89 and 100%, respectively, for the Oxoid Xpect L...
متن کاملSensitivity of three urinary antigen tests associated with clinical severity in a large outbreak of Legionnaires' disease in The Netherlands.
In 1999 an outbreak involving 188 patients with Legionnaires' disease (LD) occurred among visitors to a flower show in the Netherlands. Two enzyme immunoassays (Binax and Biotest) and one immunochromatographic assay (Binax NOW) were tested, using urine samples from LD patients from the 1999 outbreak. Sensitivity was calculated using positive culture and/or seroconversion as the "gold standard" ...

The Binax and the Biotest urinary antigen kits for the detection of Legionnaires' disease caused by organisms other than Legionella pneumophila were compared by testing 45 urine samples from non-Legionella pneumophila serogroup 1 patients previously positive in a broad-spectrum enzyme-linked immunosorbent assay (ELISA). Eighteen were positive with the Binax kit, and 13 were positive with the Bi...
متن کاملBinax and biotest Legionella urinary antigen kits.
The article of Robert F. Benson et al. entitled “Evaluation of the Binax and Biotest urinary antigen kits for detection of Legionnaires’ disease due to multiple serogroups and species of Legionella” (1) states the following in the abstract: “Eighteen were positive with the Binax kit, and 13 were positive with the Biotest.” This statement is misleading since data in both the article and Table 1 ...

The clinical utility of Legionella urinary antigen assays for the diagnosis of Legionnaires' disease was assessed by using samples from 317 culture-proven cases. The sensitivities of the Binax enzyme immunoassay (EIA) and Biotest EIA were found to be 93.7 and 94.4% for travel-associated infection and 86.5 and 76.0% for community-acquired infection but only 44.2 and 45.7% for nosocomially acquir...
