Digestive System Testing: How It Works for Gut Health

Digestive system testing reveals what’s happening inside your gut by examining the microbial community and its interactions with digestion and immunity. In most tests, stool samples are analyzed to identify which microbes are present, how abundant they are, and what functions they support—such as fiber breakdown, metabolite production, and barrier health. The results typically report on microbial diversity, key bacterial abundances, and the activity of metabolic pathways, and they can be interpreted alongside your lifestyle data, like a 3-day food diary, to show how your choices affect gut function. When doctors or wellness teams review these results, they translate them into care plans—from dietary tweaks to targeted probiotics—that support your digestive system health. Inside the InnerBuddies ecosystem, the digestive system testing experience is powered by a white-label Gut Health Operating System that companies can deploy to build their own gut testing products. The platform is modular and feature-rich: the Gut Microbiome Health Index (a score from 0 to 100 that signals overall gut health) derives from an exclusive IP deal with EAFIT University in Colombia; Bacteria Abundances displays your levels for a top-40 set of bacteria and how you compare with a healthy cohort; Bacteria Functions groups microbial activities into positive or negative categories and benchmarks them against norms. The platform also offers Target Group Analysis to drill into how the microbiome supports specific goals—Healthy Aging, Endurance Sport, Skin & Hair Health, and more—so recommendations can be aligned with your lifestyle. Beyond data, InnerBuddies translates insights into practical steps through personalized nutrition advice. By comparing your 3-day food diaries with stool results, the system shows how individual foods can influence your gut and suggests tailored probiotics and prebiotics. This is how digestive system testing translates into concrete care actions. For consumers curious about taking charge of their gut health, you can explore the solution directly with InnerBuddies microbiome test and, for ongoing support, a subscription option on Gut Health Membership. Both paths reflect InnerBuddies’ commitment to actionable digestive system testing and personalized care. Organizations looking to offer their own branded gut health products can partner with InnerBuddies and leverage the same robust platform and insights.
