Segmentation Analysis
- Product Analysis: In 2024, the instruments segment dominated the microbiology testing market with a 58.3% share. This growth is driven by increasing demand for precise, automated diagnostic tools in clinical and research settings. Instruments such as PCR machines and spectrophotometers offer high-speed and reliable detection of pathogens. The growing burden of infectious diseases and the need for efficient diagnostic workflows are fueling investment in advanced instruments, especially as healthcare systems prioritize improved diagnostic infrastructure and faster patient management.
- Test Type Analysis: Bacterial testing led the test type segment with a 54.2% share, driven by the global burden of bacterial infections and the rising demand for accurate diagnostics. Common tests include culture methods, antigen detection, and PCR assays. The urgency to combat antimicrobial resistance (AMR) has further increased focus on rapid identification of bacterial strains. Continued technological innovation and the need for precise pathogen detection are expected to accelerate the expansion of bacterial testing across both clinical and public health settings.
- Application Analysis: Respiratory diseases accounted for 41.5% of the application segment, the largest share in 2024. The increasing incidence of infections such as pneumonia, tuberculosis, and COVID-19 has intensified the demand for fast and accurate microbiology testing. Development of rapid respiratory pathogen diagnostics and global emphasis on infection control are key drivers. Rising cases of chronic respiratory conditions and enhanced public health awareness are expected to sustain the segment’s growth in both hospital and community diagnostic environments.
- End-User Analysis: Hospitals dominated the end-user segment in 2024, securing a 55.3% revenue share. This is attributed to high patient throughput and the critical need for reliable infection diagnostics in clinical care. Hospitals heavily rely on microbiology testing for diagnosing and managing infectious diseases, especially in critical care units. Increasing hospital-acquired infection (HAI) rates and investments in laboratory upgrades are strengthening diagnostic infrastructure. These factors collectively support the continued dominance of hospitals in the microbiology testing market.

Regional Analysis
North America held the largest share of the microbiology testing market in 2024, accounting for 38.8% of global revenue. This dominance is attributed to rapid technological advancements, a strong focus on infectious disease surveillance, and growing demand for rapid diagnostic tools. According to the CDC, the 2024 flu season witnessed a surge in respiratory-related hospital visits, significantly increasing the demand for microbiological diagnostics.
Additionally, the FDA approved over 50 biologics and biosimilars in 2023, many of which required rigorous microbiology testing during development. The U.S. Department of Health and Human Services allocated US$ 500 million in 2023 to strengthen the national stockpile of diagnostic tools, reflecting heightened public health preparedness.
Meanwhile, the Asia Pacific region is projected to register the highest CAGR during the forecast period. Government initiatives in India, China, Japan, and Australia are focusing on expanding diagnostic infrastructure and improving access to testing services. India increased healthcare infrastructure spending by 20% in 2023, while Japan and Australia allocated millions to enhance diagnostic capabilities. These efforts, combined with growing awareness of infection prevention, are expected to drive microbiology testing demand across the region.
Emerging Trends
- Expansion of Rapid Molecular Diagnostics: Rapid molecular tests are increasingly replacing traditional culture methods. Since 2011, WHO-recommended molecular assays such as Xpert MTB/RIF for tuberculosis have become standard, offering results in under two hours with high sensitivity and specificity. These tests enable earlier detection of drug-resistant pathogens and improved patient management, particularly in high-burden regions, by reducing reliance on slower microscopy and culture techniques.
- Growth of Wastewater Surveillance as an Early-Warning Tool: Wastewater monitoring programs have been scaled up to detect pathogens shed by infected individuals, symptomatic or not. The U.S. CDC’s National Wastewater Surveillance System now covers over 1,500 communities approximately 45% of the U.S. population—and updates data weekly for SARS-CoV-2, influenza A, RSV, and mpox. This approach provides up to several weeks’ advance notice of rising infections, allowing public health actions to be taken before clinical cases surge.
- Integration of Genomic Sequencing in Routine Surveillance: Public health laboratories are adopting next-generation sequencing (NGS) to characterize pathogens at the genomic level. Supported by the CDC’s Advanced Molecular Detection program, these efforts enable tracking of emerging variants and antimicrobial-resistance genes directly from clinical and wastewater samples. Genomic data enhance outbreak investigations and inform vaccine strain selection for influenza and other mutable pathogens.
- Strengthening of AMR Diagnostic Capacity through Standardized Surveillance: The WHO’s Global Antimicrobial Resistance and Use Surveillance System (GLASS) now involves over 109 countries and territories, promoting standardized methods for antimicrobial-susceptibility testing (AST) and data sharing. Increased laboratory capacity for AST—including both phenotypic and molecular analyses—supports more accurate resistance profiling, guiding treatment guidelines and stewardship programs worldwide.
Use Cases
- Tuberculosis Diagnosis with Rapid Molecular Assays: In 2023, global TB diagnoses rose to 8.2 million cases, with bacteriological confirmation increasing from 55% (2018) to 63%. WHO recommends Xpert MTB/RIF Ultra and Truenat assays as initial tests. These assays deliver results in around 80 minutes and improve detection of rifampicin-resistant TB, particularly in smear-negative and HIV-co-infected patients.
- Early Detection of Community Infection Trends via Wastewater: The CDC’s NWSS monitors untreated sewage in 1,500+ U.S. locations, covering an estimated 151 million people (45% of the population). By testing weekly for pathogens such as SARS-CoV-2, influenza A, and mpox, the system provides an early snapshot of community disease burden, enabling targeted interventions before clinical cases peak.
- Antimicrobial-Resistance Surveillance through GLASS: As of 2025, GLASS engages 109 countries and supports sampling of key pathogens from routine clinical specimens. Participation has led to the aggregation of data on over 2 million bacterial isolates annually, informing national treatment guidelines and global stewardship policies to combat rising AMR trends.
- Standardized Laboratory Data Management with WHONET: WHONET is deployed in over 2,300 laboratories across 130+ countries for managing and analyzing microbiology data. By standardizing AST results globally, WHONET enhances comparability of resistance patterns, supports outbreak detection, and informs public health decision-making on antimicrobial use.
Conclusion
The global microbiology testing market is undergoing transformative growth, driven by the rising prevalence of infectious diseases, technological advancements, and expanding diagnostic infrastructure. With a projected value of US$ 13.8 billion by 2034, the market is supported by strong demand across healthcare, pharmaceutical, and environmental sectors.
Key developments such as rapid molecular diagnostics, wastewater surveillance, genomic sequencing, and global AMR monitoring are reshaping disease detection and response strategies. As governments and health agencies prioritize early detection and data-driven decision-making, microbiology testing will continue to play a vital role in safeguarding public health and strengthening global health security
