Method Comparison of the ImmuView L. Pneumophila and L. Longbeachae Urinary Antigen Test with the BinaxNOW Legionella Urinary Antigen Card for Detection of Legionella Pneumophila Serogroup 1 Antigen in Urine.

We compared the clinical performance of the ImmuView L. pneumophila and L. longbeachae urinary antigen test (SSI Diagnostica A/S, Hillerød, Denmark) to that of the BinaxNOW Legionella urinary antigen card (Binax; Abbott, Lake Buff, IL) using urine specimens from patients suspected of having pneumonia. In total, 100 frozen urine samples (derived from 50 Legionella cases and 50 noncases) were analyzed with both tests, as were 200 nonfrozen prospectively collected samples.
