The global Legionnaire Disease Testing Market is set for robust expansion, projected to grow from USD 378.1 million in 2025 to USD 895.2 million by 2035, registering a compound annual growth rate (CAGR) of 9.0%, according to new industry analysis. This growth underscores a rising global focus on early disease detection, infection control, and the development of advanced diagnostic technologies.
Market Growth Drivers
Legionnaire disease, a severe form of pneumonia caused by Legionella bacteria, continues to pose significant risks, especially in hospitals, elderly populations, and waterborne transmission settings. Increasing healthcare awareness, coupled with the prevalence of hospital-acquired infections, has led to greater adoption of rapid and reliable testing solutions.
The World Health Organization (WHO) notes that 75–80% of diagnosed cases occur in individuals aged 50 years or older, with men more frequently affected. This demographic profile continues to shape demand for quick diagnostic interventions.
Recent innovations—such as point-of-care devices, urinary antigen tests, and PCR-based solutions—are enabling clinicians to provide faster, more accurate results, significantly improving patient outcomes.
Segment Insights
- Devices Lead Growth: Devices are expected to dominate the market with a 39.4% share in 2025, driven by automation, improved sensitivity, and reduced manual errors in hospital and laboratory workflows.
- Urinary Antigen Test Preferred: This test will hold 45.7% market share in 2025, favored for its rapid, non-invasive detection and strong role in outbreak investigations.
- Hospitals as Key End-Users: Hospitals are projected to account for 52.3% of market revenue in 2025, underscoring the importance of in-house diagnostic capabilities for infection control.

Market Positioning & Competitive Analysis
The Legionnaire disease testing market is positioned at the intersection of public health urgency and technological innovation. With healthcare systems worldwide prioritizing infection prevention, companies that invest in automation, point-of-care diagnostics, and integrated platforms are expected to capture significant market share.
While global giants such as Abbott, Roche, and Thermo Fisher drive innovation with extensive R&D investments, niche players like Aquacert and Albagaia are carving out space by offering specialized water testing services and compliance solutions. This balance between multinational scale and specialized expertise is shaping a highly dynamic competitive environment.
The market’s future will be influenced by regulatory frameworks, clinical adoption, and healthcare infrastructure investments. Regions with strong infection control policies—particularly North America and Europe—will continue to lead, while Asia-Pacific emerges as the fastest-growing market due to rising healthcare modernization.
Growth Factors
- Rising prevalence of waterborne infections and hospital-acquired diseases.
- Expanding elderly population with higher susceptibility.
- Technological advancements in rapid diagnostic devices and PCR systems.
- Increased hospital focus on infection control and in-house diagnostic capabilities.
- Government and nonprofit awareness campaigns driving early testing adoption.
However, challenges such as limited healthcare infrastructure in emerging regions, lack of awareness, and shortage of skilled healthcare providers may restrain growth in certain markets.
Outlook
With a projected USD 895.2 million valuation by 2035, the Legionnaire Disease Testing Market is poised for sustained global growth, offering significant opportunities for diagnostic companies, healthcare providers, and investors. As innovation accelerates, the market is expected to transition from reliance on traditional laboratory methods toward fully integrated, automated, and rapid diagnostic ecosystems.
