Legionella Testing Market Size, Share, Growth, Trends, and Global Industry Analysis: By Application Type (Water Testing, IVD Testing), By Product (Kits and Reagents), By Distribution Channel (Hospitals, Diagnostic Labs, Others), and Region Forecast 2019-2030

Legionella Testing Market size was valued at US$ 292.5 million in 2023 and is projected to grow at a significant CAGR of 9.7% from 2024-2030. Legionella bacterial species are present in freshwater reservoirs and are responsible for legionnaire's disease, a respiratory ailment. The market is anticipated to increase fast during the projected period due to the increased incidence and prevalence of this disease, pushing up demand for testing kits.

Furthermore, the rising incidence of hospital-acquired legionella infection and increased testing frequency in these facilities due to stringent regulations will drive demand for such effective products in the near future. The presence of diverse species in water reservoirs like ponds, lakes, swimming pools, warm water showers, and commercial building water supply pipes is increasing health hazards. Exposure to legionellosis outbreaks increases the risk of morbidity and mortality. Thus, stringent monitoring of water reservoirs and the launch of rapid testing methods for onsite water testing are anticipated to promote market growth. In the market, the Urinary Antigen Test (UAT) Segment is Expected to Hold a Major Market Share. This test category is predicted to develop rapidly over the projection period due to distinct advantages such as detecting whole serogroups associated with legionella and quick testing. Due to the expensive cost of PCR procedures, their general application in the current economy is limited.
