Segmentation Analysis

By Product, Manual Tests Segment Dominates the Antimicrobial Susceptibility Testing Market

In 2023, the manual tests market segment captured the largest share of the antimicrobial susceptibility testing (AST) market with 54% market share because of its extensive use, affordability, and simplicity of deployment in clinical microbiology laboratories, especially in low- and middle-income nations. The tests, such as disk diffusion and broth dilution techniques, are the gold standard for AST because they are trusted and accepted by regulatory bodies. The absence of automated system infrastructure in most areas and the versatility of manual systems in screening a wide variety of pathogens also helped the segment’s dominance endure.

By Application, Susceptibility Testing Segment Dominates the Antimicrobial Susceptibility Testing Market

In 2023, the susceptibility testing segment dominated the market with a 47% market share because of its crucial role in determining proper antimicrobial therapy and countering the worldwide threat of antibiotic resistance. This application is a cornerstone of clinical microbiology, enabling healthcare professionals to decide the best treatment for bacterial infections. Due to increasing cases of multidrug-resistant organisms, susceptibility testing has emerged as a top priority in hospital and diagnostic contexts.

By Technique, Disk Diffusion Segment Dominates the Antimicrobial Susceptibility Testing Market

In 2023, the disk diffusion market captured the largest share of the market with a 40% market share due to its ease of use, economy, and long clinical track record. The method is embraced by international health authorities and laboratories globally for its ease of use and precision in testing for bacterial susceptibility. Disk diffusion is especially a popular choice in resource-poor facilities since it requires little equipment. Its wide application in testing a range of pathogens and ease of use in standard clinical workflows further cement its supremacy.

By End-Use, the Hospitals Segment Dominates the Antimicrobial Susceptibility Testing Market

In 2023, the segment of hospitals dominated the antimicrobial susceptibility testing (AST) market with a 39% market share because of the large number of infectious disease cases that need early diagnosis and effective treatment. AST is heavily dependent upon hospitals to treat drug-resistant or serious infections in their inpatients, and these centers are the largest consumers of manual and automated testing solutions.
