Antimicrobial Susceptibility Testing Market Size & Share Analysis - Growth Trends & Forecasts (2025 - 2030)

Global Antimicrobial Susceptibility Testing Market Trends and Insights

Global Spread of Antimicrobial Resistance Escalating Healthcare Burden

Antimicrobial resistance drove USD 66 billion in annual economic losses and is projected to reach USD 159 billion by 2050 under present trends, prompting health systems to fund rapid testing platforms that cut inappropriate prescribing.^{[2]Source: World Organisation for Animal Health, “Forecasting the Fallout from AMR,” woah.org} The WHO target of a 10% annual reduction in bacterial AMR deaths has triggered stewardship programs in 170 nations, with 67% now linking prescribing to susceptibility data. Hypervirulent carbapenem-resistant Klebsiella pneumoniae underscores the demand for platforms that detect virulence and resistance markers in one run. These pressures are acute in regions where projected AMR mortality will rise 68% by 2050, elevating the need for cost-effective point-of-care testing. Hospitals now view rapid AST as a necessary investment that reduces length of stay and improves outcomes.

Pharma and Biotech Adoption of AST in Antibiotic Pipelines

FDA guidance mandates coordinated drug-diagnostic development, pushing antibiotic sponsors to embed AST protocols from preclinical stages. The CARB-X program added USD 10 million in 2024 for diagnostic-therapeutic combinations, reflecting industry conviction that companion AST drives commercial success. Lefamulin approval paired with defined AST methods demonstrates how early diagnostic integration improves regulatory speed. Firms expect earlier resistance monitoring to lift trial success and extend exclusivity through precision labeling. As a result, pharma demand fuels new revenues for platform suppliers.

Precision-Medicine Push for Pathogen-Specific Therapy

Ultra-rapid platforms deliver identification in 88 minutes and full susceptibility in 148 minutes, eclipsing the 16-hour culture workflow and raising correct therapy in sepsis from 48% to 97.6% when combined with AI prediction. Syndromic systems like Unyvero show 51% full concordance while detecting more co-infections in pneumonia cases. Each hour of treatment delay raises mortality 7.6% in sepsis, reinforcing return on investment arguments for rapid AST deployment. Hospitals prioritise platforms that couple organism identification with susceptibility profiles to guide narrow-spectrum therapy and protect last-line agents.

Rapid Phenotypic AST Devices (<2 H) for Point-of-care

QuantaMatrix launched a platform marketed as the fastest AST, underscoring competition for sub-2-hour results that affect bedside prescribing. VITEK REVEAL averages 5.5 hours from positive blood culture across 176 bug-drug pairs, showing commercial viability. FDA classification of multiplexed AST systems into Class II special controls signals regulatory support while maintaining quality standards. Emergency departments and ICUs adopt these products first because empirical therapy choices are made within hours. As turnaround improves, laboratories shift away from overnight culture workflows.

Fragmented and Stringent Device-Approval Pathways

Companies face divergent requirements across FDA, IVDR, CLSI, and EUCAST frameworks, often adding 12-18 months to European timelines versus the United States. Local studies demanded by India or Brazil further delay launches. AI-enabled platforms require re-validation for each population, raising costs and diverting resources toward high-value markets first. The result is slower roll-out into regions with the highest resistance burden.

High Capital Cost and Poor Reimbursement for Analyzers

Automated AST platforms exceed USD 200,000, and rapid tests cost 3–5 times more per assay than conventional methods yet often reimburse at similar rates, discouraging uptake in Asia Pacific and rural hospitals. Low-volume sites struggle to justify investment, while insurers remain hesitant to reward faster, pricier testing even when research shows shorter hospital stays. LMIC laboratories face annual budgets below the price of a single high-throughput analyzer, prompting demand for low-cost portable kits.

Segment Analysis

By Product: Automation Drives Laboratory Transformation

Manual products continued to dominate with 51.25% of antimicrobial susceptibility testing market share in 2024 owing to disk diffusion and broth microdilution usage in smaller laboratories. Automated instruments are predicted to grow at a 6.98% CAGR as consolidation favors high-throughput and standardized workflows. The segment hierarchy spans consumables, semi-automated, and fully integrated analyzers that cut hands-on time and enhance traceability. Laboratories in high-income countries prioritize full automation to mitigate labor shortages and meet documentation standards. Manufacturers bundle software analytics that flag resistance trends and enable remote support, converting one-off hardware sales into recurring service revenue.

Consumables and reagents generate predictable income as test volumes climb in reference centers. Rapid analyzers delivering sub-2-hour phenotypic results attract critical care units willing to pay premium prices for faster treatment decisions. In emerging markets, semi-automated options balance cost and efficiency, gradually shifting demand toward fully automated lines as capital financing improves. The continued dominance of manual kits in veterinary and public health settings ensures stable baseline demand across the forecast.
