GI Stool Testing Market 2025–2033: Key Players Overview

According to FutureWise analysis, the GI stool testing market in 2025 is US$1.10 billion, and is expected to reach US$1.83 billion by 2033 at a CAGR of 6.57%. The gastrointestinal (GI) stool testing market is experiencing steady growth due to the increasing prevalence of gastrointestinal disorders, such as colorectal cancer and inflammatory bowel disease (IBD), as well as infections like C. difficile. This expansion is driven by a rising incidence of these disorders, greater awareness regarding early disease detection, and advancements in diagnostic testing technologies. Additionally, an aging population and a growing preference for non-invasive diagnostic methods are further contributing to market growth. GI stool testing involves analyzing stool samples to diagnose intestinal infections or diseases. Common gastrointestinal disorders include bowel inflammation, malabsorption issues, and cancer. The market is being propelled by the rise in GI diseases, attributed to unhealthy eating habits, busy lifestyles, and an aging demographic, which is increasingly susceptible to gastrointestinal infections. Both public and private sectors are expected to enhance investments in healthcare, further fueling market growth.There is a significant shift towards non-invasive testing, with an emphasis on home-based testing kits and point-of-care diagnostics, improving patient compliance and accessibility. The bacterial pathogen detection segment is anticipated to hold the largest market share in 2024, due to the high prevalence of bacterial infections and the availability of advanced diagnostic tests for their detection.Many studies have demonstrated a link between gut health and overall health. The gut microbiota specifically mediates the effects of nutrition and other factors on health, influencing digestive, immune, metabolic, and neuroendocrine processes. By employing appropriate methods to assess GI health, practitioners can identify the underlying causes of chronic illnesses. For instance, stool DNA tests, commonly referred to as FIT-DNA tests, detect traces of DNA (genetic material) released by polyps or colon cancers, rather than simply looking for blood. The Cologuard test is a popular screening tool of this type, as it can identify blood in stool samples and detect ten other factors associated with colon cancer.

Recent developments in the GI stool testing market include the launch of ColoClear by Circle (ColoClear) in June 2022 by Prenetics Group Limited, a global leader in genomic and diagnostic testing. This innovative, non-invasive, at-home screening test is designed to detect early signs of colorectal cancer and was introduced in Hong Kong.
