"Designing Growth Strategies is in our DNA"
The global Legionella testing market size was valued at USD 290.4 million in 2022. The market is projected to grow from USD 317.3 million in 2023 to USD 600.1 million by 2030, exhibiting a CAGR of 9.5% during the forecast period.
The global market is predicted to experience significant growth due to the increasing prevalence of Legionnaire's disease, Pontiac fever, and pneumonia. Moreover, the growing awareness about sanitation and a heightened emphasis on preventing infectious diseases are expected to boost the demand for Legionella testing kits. Legionella is a bacterial species that predominantly thrives in freshwater sources such as showers, bathtubs, ponds, swimming pools, and other water sources. Stringent regulations were established for the regular testing of freshwater sources, especially after the prevalence of Legionella infection in the U.S. in 1997. The rising occurrence of the disease is anticipated to drive the growth of the global market.
Water in many commercial building storage systems was left unused for extended periods, making it susceptible to the growth of Legionella species. Many countries' governments have recommended mandatory testing of these water sources before resuming operations at these sites to prevent a Legionella outbreak.
Decrease in Water Testing During the Pandemic Impeded Market Growth
The market witnessed slow growth during the pandemic due to the temporary halt in manufacturing, disruption in the supply chain, and a shift of the healthcare system's focus toward managing COVID-19. The clinical presentation of Legionella disease is similar to COVID-19 infection, leading to higher testing rates for the coronavirus and a reduction in Legionnaires' disease testing, thus hampering market growth.
However, the market is expected to grow significantly in the post-pandemic era. The pandemic-related lockdowns resulted in stagnant water in empty buildings, potentially increasing the proliferation of Legionella bacteria.
Thus, the rising government emphasis on testing water for the presence of Legionella in the post-pandemic period is increasing the demand for Legionella testing, contributing to market growth.
Growing Adoption of Rapid Testing Methods such as Urine Antigen Testing and PCR to Accelerate Market Growth
The technologies powering molecular diagnostics are rapidly evolving to address the rising cases of infectious diseases. The conventional Legionella testing method, utilizing microbial culture technology, is time-consuming and laborious. However, it was the most preferred test method over the urine antigen test until the emergence of the PCR test, primarily due to its ability to detect Legionella species serogroups. PCR is highly sensitive, with a sensitivity of 95-99%, can detect all serotypes of Legionella species, and provides rapid results. The increasing availability of real-time PCR kits and its expanded geographic reach have resulted in enhanced adoption of this test method globally.

Growing Prevalence of Legionnaire Disease to Stimulate Market Growth
Legionella bacterial species are commonly found in freshwater reservoirs with an average temperature of 20 to 40 degrees Celsius. They are responsible for causing a respiratory disease known as Legionnaire’s disease. The market is expected to grow rapidly during the forecast period, driven by the increasing incidence and prevalence of this disease, leading to a rise in demand for testing kits.
Moreover, the rise in the incidence of hospital-acquired Legionella infection and the increasing frequency of testing in these facilities due to stringent regulations will drive the demand for such effective products in the near future.
Stringent Regulations for Regular Water Testing to Spur Market Growth
The presence of various Legionella bacterial species in water reservoirs such as ponds, lakes, swimming pools, warm water showers, and water supply pipes of commercial buildings is a growing public health concern. Outbreaks of Legionellosis result in an increased risk of morbidity and mortality among exposed individuals. Therefore, the suspicion of an outbreak warrants immediate action. The World Health Organization (WHO) provides information and guidance on the assessment of Legionella risk and its proper management in seven principal documents. These documents offer guidance on the evaluation and management of risks associated with water sources, pools, cooling towers, and spa baths. The governments of many countries have enacted regulations to manage Legionella in various types of water systems.
Legionella infection is a well-recognized and commonly occurring health concern in developed nations. In response to this, various governments have enacted stringent regulations for diagnosing associated diseases and conducting regular testing of potential sources of infection. On the other hand, there is limited awareness about the bacteria and the diseases associated with it in emerging regions of the world. The disease is underdiagnosed in many countries due to a lack of proper definition, guidelines, and diagnostic facilities, posing a significant challenge to market growth of Legionella testing.
Studies regarding awareness of this infection in India have found that sporadic cases often go unnoticed due to the burden of other diseases such as bacterial and viral pneumonias and tuberculosis. Thus, limited awareness about the diseases, insufficient diagnostic infrastructure, and slow adoption of advanced diagnostic tools with high costs, such as real-time PCR, are some of the major factors hampering the growth of the market.
Urine Antigen Testing (UAT) Segment Dominates Owing to Rising Preference from People in Developing Regions
Based on type, the market is segmented into culture media, urine antigen testing, Polymerase Chain Reaction (PCR), serology tests, and direct antibody fluorescent methods. The urine antigen testing segment held the largest share in 2022. This is the most commonly used laboratory test for detecting the Legionella bacterium in urine. It can provide results on the same day of sample collection, unlike culture media methods that require 7 to 8 days. Moreover, it is a cost-efficient test and is more preferred among people in underdeveloped or developing regions. These factors are set to drive the segment's growth over the forecast period. However, the test can only detect LP1 species of Legionella, which may affect the segment's growth to some extent.
On the other hand, the Polymerase Chain Reaction (PCR) segment is anticipated to witness lucrative growth in the forecast period. PCR results in accurate, sensitive, and precise results, making it a preferable choice for testing samples.

Clinical Laboratories Segment Dominated Market Due to the Increasing Disease Prevalence
Based on end-user, the market is segmented into hospitals and clinics, clinical laboratories, and others which including environmental testing sites. Among them, the clinical laboratories segment registered the highest revenue and is anticipated to continue this dominance during the forecast period. This is attributable to the growing prevalence of Legionnaire's disease, increasing awareness, and a rise in the penetration of advanced tests for Legionella infection diagnosis.
The others segment, which includes environmental testing apart from the clinical testing of Legionella bacterium, is anticipated to expand at a rapid rate over the study period. This is owing to the introduction of onsite testing methods and the enforcement of stringent regulations for routine water check-ups.
Geographically the market is studied across North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa.
