ImmuView test accurately detects Legionella longbeachae in urine samples.
Performance assessment of five Legionella urinary antigen tests for Legionella pneumophila and Legionellalongbeachae.
Francesca Azzato et al. · Pathology · 2026
Background
In parts of Asia and the Western Pacific, Legionella longbeachae is also a common cause.
Results
sensitivity and specificity for L. longbeachae
The ImmuView test correctly identified all L. longbeachae infections and those without it
More results
Legionnaires' disease (LD) is a severe pneumonia caused by Legionella species., with Legionella pneumophila serogroup 1 (SG1) responsible for 70-80% of cases in Europe and the United States.
Most urinary antigen tests (UATs) target only L. pneumophila SG1, limiting detection of other species.
More results
A total of 81 urine samples were tested across all assays, except STANDARD F (n=80).

Conclusion · 1 of 2
In regions where L. longbeachae represents a substantial proportion of Legionella infections, the ImmuView assay offers an effective primary screening approach since it can simultaneously detect both L. pneumophila SG1 and L.
Conclusion · 2 of 2
longbeachae in a single test, thereby minimising reliance on slower diagnostic methods such as culture or PCR.
