Antimicrobial Susceptibility Testing Market Size, Share, Growth Analysis, By Test type(Phenotypic testing, genotypic testing, and rapid testing), By End user(Hospitals and diagnostic laboratories, research and academic institutes, and pharmaceutical and biotechnology companies), By Product type(Instruments, reagents and kits, and software and services), By Region - Industry Forecast 2025-2032

Antimicrobial Susceptibility Testing Market size was valued at USD 3.98 Billion in 2023 and is poised to grow from USD 4.19 Billion in 2024 to USD 5.99 Billion by 2032, growing at a CAGR of 5.2% during the forecast period (2025-2032).

Antimicrobial susceptibility testing market is a crucial sector in the healthcare industry, essentially in infectious disease management and microbiology. The market is considerably driven by the rising cases of antibiotic-resistant bacteria that has remarkably increased the demand for AST or antimicrobial susceptibility testing for efficient treatment choices. Increasing prevalence of infectious diseases on the global scale is considerably driving the demand for reliable and accurate diagnostic technologies. Furthermore, growing advancements and innovations in diagnostic tools like automation in testing procedures and molecular methods are improving the precision and efficacy of antimicrobial susceptibility testing. The market is also positively impacted by the rising number of players, allowing providers to choose the suitable testing option. 

Nonetheless, the global antimicrobial susceptibility testing market is anticipated to be hampered by the significant cost of AST technologies, lack of standardization, and growing complexity of procedures. The cost of AST technologies could create barriers to adoption, especially among the middle-income and low-income regions. This could restrict the broad adoption and hamper market growth. lack of standardized norms and procedures may result in variations in test outcomes, affecting reliability. Some of the AST techniques may be complex and demand specialized training. This could incur costs and be a barrier for a few healthcare settings. Yet, the market is opportune to factors like the growing trend of POC testing, offering prospects for user friendly AST solutions and improvements in regenerative medicine.
