Antibiotics are used to deal with infections or diseases caused by bacteria. If the antibiotic can deal with the infection, it is classified as effective. By conducting the antibiotic susceptibility test, doctors can choose the most potent antibiotic for treating the patient's bacterial infection. This ensures that the patient gets the most effective treatment.
| Aspect | Definition |
|---|---|
| Susceptible | The antibiotic can effectively inhibit or kill the bacteria at safe concentrations, making it a viable treatment option. |
| Resistant | The bacteria can survive and multiply even in the presence of the antibiotic, rendering the drug ineffective. |
| Intermediate | The bacteria may respond to the antibiotic at higher doses or under certain conditions, but it is not the best option for treatment. |
However, there are some cases where the patient has to undergo treatments with longer antibiotic doses. Due to this, the bacteria tend to become resistant to the antibiotics. With the help of an antibiotic susceptibility test, the healthcare provider can determine what antibiotics are able to fight the bacterial infection. Additionally, resistance monitoring keeps track of the antibiotic resistance level.
Moreover, tracking antibiotic resistance during antibiotic therapy can improve the quality of patient care quality. Samples such as blood or urine need to be collected to conduct the antibiotic susceptibility test. The sample is cultured to identify the bacteria causing the disease, and the pathogenic bacterial strain is then isolated.
Moreover, there are different methods of testing, such as broth dilution, disk diffusion, or automated systems. The bacteria thus tested are classified as susceptible, intermediate, or resistant. This categorization gives direction to the administration of the appropriate dosage for the medication.
Rise in Bacterial Infections
Bacterial infections have been on the rise for a while, and a large population in the world is suffering from some infection or another. People in families with low or moderate incomes are prone to suffering from various diseases. Antimicrobial susceptibility testing is used in hospitals to test out infections such as tuberculosis or those due to hygiene problems, and the results are generally accurate.
Some individuals are given a treatment that may not suit them; therefore, they require a personalized treatment plan. Antimicrobial susceptibility testing helps recommend precision medicines. The government also plays a vital role in increasing research in this field by funding research programs and organizing awareness campaigns. Additionally, the market is getting increasingly competitive.

Innovations in Antimicrobial Susceptibility Testing to Propel Adoption
New strains of bacteria and the mechanism of their resistance are being studied, and this will be possible as improvements keep happening in antimicrobial susceptibility testing methods. Incorporating tailored approaches leads to enhanced precision diagnostics, which will be a major driver behind the market growth.
Additionally, steps are expected to be taken in regions with resource constraints. The areas that are not equipped with the best healthcare facilities will also get access to this testing due to faster and cheaper testing methods.
Advancements in Genomic and Molecular Testing
With growing research in the field of molecular and genomic testing, antimicrobial susceptibility testing methodologies have become more advanced. Moreover, technologies, including next-generation sequencing (NGS), PCR, and CRISPR-based diagnostics, allow for quicker detection of strains, which streamlines healthcare processes.
Additionally, these techniques are growing in popularity in antimicrobial susceptibility testing workflows for the formulation of precision medicines. Moreover, CRISPR-based tools can offer results within minimal time, which considerably decreases the diagnostic timeline.
High Initial Investment and Problems with Standardization May Limit Uptake
The laboratories that test for antibiotic susceptibility need a lot of finance due to the requirement for sophisticated testing machines. Thus, it is quite expensive to buy and maintain them. Additionally, the testing time frame might be long because of processing, which might lead to postponement of results, and in certain conditions, the test must be repeated several times for better accuracy. Moreover, upgrades to the processors can also be costly and complicated.
Furthermore, different labs can have different testing protocols, and there is a possibility of errors because of such a lack of standardization. The handling of extensive data can be tedious, too. Additionally, the setup of the labs is quite a challenge in places where the infrastructure and funding are already very poor.
Ongoing Efforts for the Development of Innovative Instruments to Foster Segment Revenue

| Top Product Type | Instruments |
| Market Share in 2025 | 40.6% |
By product, the market is segmented into instruments, software & services, and kits & reagents. The instruments segment is expected to account for nearly 40.6% market share in 2025. New-generation antimicrobial susceptibility testing techniques are progressing toward more automatic and less manual labor instruments.
The instruments ensure that the testing happens at high speed and give the doctors a chance to monitor the testing process in real-time. These instruments are vital in big hospitals and labs, where there is a good investment for them. Moreover, there is an ongoing effort to develop more powerful devices that have more advanced features. The instruments would see constant development to gain higher accuracy.
Surging Sepsis Occurrence to Drive Uptake
By application, the market is segmented into sepsis, respiratory infections, gastrointestinal infections, meningitis & encephalitis, endocarditis, and others. The testing method is being widely used for the treatment of sepsis owing to its accuracy in identifying pathogens. Moreover, the higher prevalence of the disease in developed and developing regions globally is contributing to segment expansion.
Rising Hospital Admissions to Bolster Demand
| Attributes | Details |
|---|---|
| Top End User Type | Hospitals |
| Market Share in 2025 | 41% |
By end user, the antimicrobial susceptibility testing market is segmented into diagnostic laboratories, hospitals, and research laboratories. The hospitals segment is expected to account for nearly 41% of the market share in 2025, driven by an increasing number of hospitalizations. Additionally, diagnostic tests are needed by many of the patients, mainly those who suffer from bacterial infections. Sometimes, when infections are severe, the patients also need to be admitted to the intensive care units (ICUs).
In such settings, the patients might need to be tested several times at different times of the day to check if the infection has become less severe. Owing to growing hospital-acquired infections, these settings also have facilities to conduct antibiotic sustainability testing. Even governments keep antimicrobial susceptibility testing as a priority and fund these projects regularly. Due to this, the hospitals contribute to a significant share of revenue in the market.
| Country/Region | CAGR (2025 to 2035) |
|---|---|
| USA | 4.90% |
| UK | 5.80% |
| China | 4.60% |
The antimicrobial susceptibility testing market in the USA is expected to grow at a high growth rate and its CAGR is expected to be 4.9% during the forecast period 2025 to 2035.
