Intestinal Function Tests: A Clear Guide to Digestive Health

Unlock clarity on digestive health with intestinal function tests—these tests analyze how your gut functions by examining the microbiome’s composition and activity. Through stool analysis, they reveal which bacteria are present and in what amounts, and how these microbes influence digestion, metabolism, and immune responses. When paired with your diet, intestinal function tests can explain why certain foods trigger discomfort or irregularity and point to targeted steps to support gut wellness. At InnerBuddies, these insights are brought to life through our Gut Health Operating System, designed to turn test data into practical, personalized guidance. Learn more about the test here: InnerBuddies microbiome test. Intestinal function tests reveal a suite of telltale signals. A Gut Microbiome Health Index—a score from 0 to 100—serves as a concise gauge of overall gut health and is supported by an exclusive IP deal with EAFIT University in Colombia. In addition, the tests report Bacteria abundances for a top 40 panel, showing how your levels compare to a healthy cohort for both beneficial and potentially problematic species. They also map Bacteria functions, categorizing each metabolic function as positive or negative, and illustrate how you stack up against healthy references in each functional category. All of this data integrates in InnerBuddies’ platform to give a clear, interpretable picture of your gut status. To explore this in practice, see the InnerBuddies test page: InnerBuddies microbiome test. Interpreting intestinal function tests becomes practical guidance for better gut wellness. The core metrics can help you identify wellness targets and track progress over time. InnerBuddies expands this with Target Group analysis, offering deep dives into how the gut microbiome behaves for specific clusters—Healthy Aging, Endurance Sport, Power Sport, Skin & Hair Health, and more—so you can tailor strategies to your life stage or goals. On top of this, the platform provides Personalized nutrition advice, drawing on 3-day food diaries and stool results to suggest foods that support your unique microbiome, as well as Personalized probiotics and prebiotics advice that aligns strains with your objectives. You can continue your journey with ongoing insights and support by visiting our Gut Health Membership page: InnerBuddies Gut Health Membership.
