What Is Covered Under Gastroenteritis Testing Market?

Gastroenteritis testing involves a series of diagnostic procedures used to identify the cause of gastroenteritis, which is inflammation of the stomach and intestines. This condition is often caused by viral, bacterial, or parasitic infections and can lead to symptoms such as diarrhea, vomiting, abdominal pain, and fever. These tests help clinicians determine the cause of gastroenteritis and guide appropriate treatment, which may include antibiotics, antivirals, or supportive care such as hydration and rest. The main types of gastroenteritis testing are viral gastrointestinal infections, bacterial gastrointestinal infections, and parasitic gastrointestinal infections. Viral gastrointestinal infections are illnesses caused by viruses that affect the stomach and intestines, leading to symptoms such as diarrhea, vomiting, and abdominal pain. It is used for bacterial strains, viral strains, and parasitic strains and provides various types of testing, such as immunoassay testing, conventional testing, and molecular diagnostic testing. It is used by various end-users, including hospitals, clinics or medical centers, research institutes, and diagnostic laboratories.

What Is The Gastroenteritis Testing Market Growth Forecast?

The gastroenteritis testing market size is expected to see strong growth in the next few years. It will grow to $5.55 billion in 2030 at a compound annual growth rate (CAGR) of 5.8%. The growth in the forecast period can be attributed to advancements in molecular diagnostic technologies, growing demand for rapid point-of-care testing, increasing funding for infectious disease research, rising adoption of integrated laboratory information systems, expansion of gastroenteritis testing in emerging markets. Major trends in the forecast period include increasing demand for rapid and accurate gastroenteritis diagnostics, rising adoption of molecular diagnostic testing methods, expansion of viral, bacterial, and parasitic testing panels, growth in point-of-care testing and hospital-based diagnostics, enhanced focus on epidemiological surveillance and outbreak management.

What Is The Driver Of The Gastroenteritis Testing Market?

The rising incidence of bacterial infections is expected to propel the growth of the gastroenteritis testing market going forward. Bacterial infections are rising due to increased antibiotic resistance, higher population density, and greater global travel, which facilitate the spread of resistant bacteria. Gastroenteritis testing is required for bacterial infections to accurately identify the specific pathogen-causing symptoms, such as diarrhea and vomiting, which informs appropriate treatment and prevents the spread of infection. For instance, in 2024, according to the GOV.UK, a UK-based organization, cases of bacteraemia caused by antibiotic-resistant bacteria a serious, risen by 9.3% since 2023, increasing from 18,740 cases in 2023 to 20,484 cases in 2024. Therefore, the rising incidence of bacterial infections is driving the growth of the gastroenteritis testing industry.

Global Gastroenteritis Testing Market Trends and Insights

Major companies operating in the gastroenteritis testing market are developing innovative products, such as molecular gastrointestinal tests, to offer high sensitivity and specificity. A molecular gastrointestinal test is a diagnostic method that uses molecular techniques, such as polymerase chain reaction (PCR), to detect and identify specific genetic material from pathogens or organisms in gastrointestinal samples. For instance, in June 2024, QIAGEN N.V., a Germany-based provider of sample and assay technologies, launched the QIAstat-Dx Gastrointestinal Panel 2. This panel is notable for its ability to rapidly and comprehensively detect up to 16 clinically relevant bacterial, viral, and parasitic pathogens responsible for most gastrointestinal infections. It utilizes real-time polymerase chain reaction (PCR) technology to amplify multiple genetic targets in a single reaction, which is a significant improvement over traditional microbiological methods that typically require 24 hours to 10 days for sample incubation.

What Are Latest Mergers And Acquisitions In The Gastroenteritis Testing Market?

In December 2024, Indian Council of Medical Research (ICMR), an India-based national medical research organization, entered into a partnership agreement with Molbio Diagnostics Pvt. Ltd. to expand the global accessibility of its advanced multiplex RT-PCR technology for detecting enteric viruses responsible for childhood gastroenteritis by leveraging Molbio’s commercialization capabilities and worldwide diagnostic distribution network.
