Background

In parts of Asia and the Western Pacific, Legionella longbeachae is also a common cause.

Results

100%

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 (urinary antigen tests) 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 polymerase chain reaction.
