Market Overview

The Global Gastroenteritis Testing Market Size industry focuses on the products and services for diagnosing the cause of gastroenteritis, a stomach and intestinal inflammation. Acute gastroenteritis caused by the norovirus, which is the most common cause of diarrhea and vomiting, affects 19-21 million people and causes around 900 deaths. In most cases, viral gastroenteritis lasts for less than 1 week, without the need for medical intervention. Stool test is performed to identify the presence of viral infections like norovirus and rotavirus, along with other health conditions affecting the digestive system. Further, there is a changing inclination towards syndromic diagnostics in clinical microbiology, for faster detection and more informed clinical decision-making in disease management.

Innovation and market expansion are anticipated as a result of major players' growing R&D investment strategies and collaborations between government health agencies, private laboratories, and biotechnology firms. Further, the integration of advanced technologies for enabling rapid, sensitive, and comprehensive pathogen detection is driving a huge surge in the market. For instance, metagenomic next-generation sequencing (mNGS) enables the identification of all pathogens in a sample in a single test, without introducing target detection bias.
