Immunoassay for the diagnosis of Legionella - Diasorin


A new assay to empower laboratory performance in detecting Legionella Disease (LD)

Legionella species are common causes of community-acquired pneumonia (CAP) in those patients requiring hospitalization.

Legionnaires’ Disease is often underdiagnosed due to the lack of sensitivity with currently available urinary antigen tests that can detect only L. pneumonia serogroup 1.

LIAISON® Legionella Urinary Ag test allows healthcare professionals to quickly and accurately identify one of the most common causes of LD: L. pneumophila serogroup-1 plus non-L. pneumophila serogroup 1 and Legionella longbeachae

How it works

LIAISON® Legionella Urinary Ag is an exclusive diagnostic solution built to detect the lipopolysaccharide antigen (LPS) for L. pneumophila serotype 1 and the new Legionella peptidoglycan-associated lipoprotein (PAL) assuring the detection of a broad-spectrum antigens serotypes.


No need for specialized staff

LIAISON® Legionella Urinary Ag runs on the LIAISON® XL and LIAISON® XS chemiluminescence analyzers in any laboratory. 


Less than an hour to results

Fast, accurate results enable patients to be treated with the suitable antibiotic within 4 hours.


High-quality, ready-to-use CLIA assay

Standardized results with automatic processing ensure optimal harmonization between urgent, specialty and routine tests.
