Regional Analysis
North America Leading the Microbiology Testing Market
North America accounted for the largest share of the global microbiology testing market, capturing 38.8% of total revenue. This leadership position can be attributed to continuous technological advancements, rising demand for rapid diagnostic methods, and heightened public awareness of infectious diseases. A significant increase in respiratory illness-related hospital visits during the 2024 flu season, as reported by the Centers for Disease Control and Prevention (CDC), resulted in the highest case levels observed in several years. This rise in infections contributed to an accelerated demand for microbiology testing services.
Market performance was further influenced by industry participants such as QuidelOrtho, which recorded a peak in flu cases affecting their revenue projections. Regulatory activity also supported market expansion. The US Food and Drug Administration (FDA) approved more than 50 biologics and biosimilars in 2023, many of which required microbiology testing for product development, safety assessment, and quality control processes. These approvals emphasized the critical role of microbiology testing in biopharmaceutical research and production.
Additionally, strategic initiatives by the US Department of Health and Human Services (HHS), including the allocation of US$500 million in 2023 for stockpiling essential medical supplies such as diagnostic tools and testing kits, further strengthened regional market growth. These developments collectively reflect the increasing reliance on microbiology testing across healthcare, pharmaceutical, and public health sectors in North America.
What role is played by infectious disease prevalence in shaping demand for microbiology testing?
Infectious disease prevalence plays a central role in determining the demand for microbiology testing because testing volumes rise in direct response to the circulation, emergence, or re-emergence of pathogens. Higher prevalence increases the number of suspected cases, which leads to a proportional rise in diagnostic requests for culture, molecular detection, antimicrobial susceptibility testing, and serological analysis. The growth in testing demand is driven by the need for early detection, accurate pathogen identification, and appropriate therapeutic decision-making.
When infectious diseases become widespread, surveillance activities are expanded, which further contributes to higher utilization of microbiology laboratories. Public health authorities and healthcare institutions typically intensify screening programs during outbreaks, thus increasing routine and emergency diagnostic workloads. The emergence of drug-resistant organisms also strengthens the requirement for detailed microbiological characterization to guide antimicrobial stewardship.
Seasonal infections, such as influenza, and global health threats, such as tuberculosis or new viral pathogens, create cyclical or sustained increases in testing needs. The demand for rapid and high-throughput diagnostic methods is elevated during such periods, as timely results are essential for containment and treatment strategies. Therefore, the prevalence of infectious diseases directly shapes market demand, driving continuous investment in advanced microbiology testing capabilities.
Asia Pacific Expected to Exhibit the Fastest CAGR
The Asia Pacific region is projected to register the highest CAGR over the forecast period. This anticipated growth is driven by rapid expansion of healthcare infrastructure, rising healthcare expenditure, and growing public awareness regarding infection prevention and early disease detection. The Indian Ministry of Health and Family Welfare (MoHFW) reported a 20% increase in government spending on healthcare infrastructure in 2023, with investment directed toward equipping hospitals with advanced diagnostic systems, including microbiology testing technologies.
Similarly, the Chinese National Health Commission (NHC) has prioritized the expansion of diagnostic capabilities, a trend expected to generate substantial demand for microbiology testing solutions. In Japan, the Ministry of Health, Labour, and Welfare (MHLW) allocated US$150 million in 2023 to enhance diagnostic capacity through the procurement of modern testing equipment.
Complementary initiatives in Australia, led by the Department of Health, focused on strengthening healthcare infrastructure and improving access to diagnostic services, particularly in remote communities. These collective investments, combined with an increasing emphasis on early detection and preventive care, are expected to significantly advance the adoption of microbiology testing across the Asia Pacific region.
