Gastroenteritis Testing Market Report 2025

This gastroenteritis testing market report delivers an in-depth analysis of the market’s key characteristics, including size, growth potential, and segmentation. It provides a detailed breakdown of the market across major regions and leading countries, highlighting historical data and future growth projections. The report also examines the competitive landscape, market share insights, emerging trends, and strategic developments shaping the market.

The gastroenteritis testing market size has grown strongly in recent years. It will grow from $3.94 billion in 2024 to $4.18 billion in 2025 at a compound annual growth rate (CAGR) of 6.2%. The growth in the historic period can be attributed to growth in global travel, rise in the population, rise in foodborne illness outbreaks, growth in healthcare infrastructure, and increasing public health surveillance initiatives.

The gastroenteritis testing market size is expected to see strong growth in the next few years. It will grow to $5.26 billion in 2029 at a compound annual growth rate (CAGR) of 5.9%. The growth in the forecast period can be attributed to the rising prevalence of waterborne diseases, the growing number of healthcare facilities, the increasing use of point-of-care testing kits, the rising incidence of viral infections, and the increasing prevalence of gastrointestinal infections. Major trends in the forecast period include technological advancements, the adoption of molecular diagnostics, the integration of AI, point-of-care testing, and telemedicine.

The increasing incidence of bacterial infections is expected to drive the growth of the gastroenteritis testing market. Bacterial infections are on the rise due to factors such as increased antibiotic resistance, higher population density, and more global travel, which facilitate the spread of resistant bacteria. Accurate gastroenteritis testing is crucial for identifying the specific pathogens responsible for symptoms such as diarrhea and vomiting, guiding appropriate treatment, and preventing further spread of infections. For example, the European Centre for Disease Prevention and Control reported in February 2024 that 4,149 confirmed cases of shigellosis were documented across 30 EU countries in 2022, with 48% of these cases linked to travel. This raised the overall notification rate to 1.5 cases per 100,000 population, indicating an increase from the rates observed in 2020 and 2021. Consequently, the rising incidence of bacterial infections is boosting the demand for gastroenteritis testing.

Key players in the gastroenteritis testing market are focusing on developing advanced products, such as molecular gastrointestinal tests, to enhance sensitivity and specificity. These tests utilize molecular techniques, such as polymerase chain reaction (PCR), to detect and identify specific genetic material from pathogens in gastrointestinal samples. For instance, in June 2024, QIAGEN N.V., a Germany-based provider of sample and assay technologies, introduced the QIAstat-Dx Gastrointestinal Panel 2. This panel can quickly and thoroughly detect up to 16 clinically significant bacterial, viral, and parasitic pathogens that cause most gastrointestinal infections. It employs real-time PCR technology to amplify multiple genetic targets in one reaction, offering a significant improvement over traditional microbiological methods, which often require 24 hours to 10 days for sample incubation.

In August 2022, SSI Diagnostica Group (SSID), a Denmark-based microbiology company, acquired TechLab for an undisclosed amount. This acquisition enables SSI Diagnostica to expand its diagnostic capabilities beyond respiratory and tropical diseases, strengthening its position in the growing field of gastrointestinal diagnostics. TechLab, a US-based diagnostics company, specializes in gastroenteritis testing.

Gastroenteritis testing consists of diagnostic procedures designed to identify the cause of gastroenteritis, which is inflammation of the stomach and intestines. This condition, often triggered by viral, bacterial, or parasitic infections, can cause symptoms such as diarrhea, vomiting, abdominal pain, and fever. These tests assist clinicians in determining the underlying cause of gastroenteritis and in guiding appropriate treatment, which may involve antibiotics, antivirals, or supportive measures such as hydration and rest.

The main types of gastroenteritis testing include those for viral gastrointestinal infections, bacterial gastrointestinal infections, and parasitic gastrointestinal infections. Viral gastrointestinal infections are caused by viruses that affect the stomach and intestines, leading to symptoms such as diarrhea, vomiting, and abdominal pain. Testing methods cover bacterial strains, viral strains, and parasitic strains, and include immunoassay testing, conventional testing, and molecular diagnostic testing. These tests are utilized by various end-users, including hospitals, clinics or medical centers, research institutes, and diagnostic laboratories.
