Inside Mosaic Diagnostics

Inside Mosaic Diagnostics: Clinical Applications of Organic Acids, Environmental, and Microbiome TestingWhat Is Mosaic Diagnostics and How Are Its Lab Tests Used in Clinical Practice?In this episode, Dr. Kate Kresge speaks with Mosaic Diagnostics CEO Scott Mattivi and Chief Medical Officer Dr. Kurt Woeller to explore how specialty laboratory testing is used in functional and integrative medicine. Mosaic Diagnostics offers tests such as organic acids, environmental exposure biomarkers, and microbiome assessments, which may help clinicians evaluate complex, multi-system presentations. These tools are typically used as part of a systems-based clinical framework, supporting pattern recognition rather than serving as standalone diagnostic tests. The discussion also explores how clinicians interpret multi-system lab data, the role of practitioner education, and how emerging technologies—such as AI-assisted tools—may support clinical efficiency and decision-making.What Does Mosaic Diagnostics Test For?Mosaic Diagnostics provides specialty lab testing commonly used in integrative and functional medicine, including:Organic acids testing (OAT)Environmental toxin and mycotoxin testingMicrobiome and gastrointestinal assessmentsMetabolic and immune-related biomarkersThese tests are designed to provide insight into biochemical pathways, microbial activity, and environmental exposures. Results are generally interpreted alongside clinical history, symptoms, and conventional labs to support individualized care.Key Clinical InsightsWhat Is Organic Acids Testing (OAT)?Organic acids testing evaluates urinary metabolites involved in intermediary metabolism. It may provide insight into:Mitochondrial functionNutrient metabolism (e.g., B vitamins, amino acids)Oxidative stress patternsMicrobial activityWhen interpreted within clinical context, OAT may support identification of metabolic patterns and inform clinical hypotheses (Gallagher, 2018).What Does Environmental Toxin Testing Measure?Environmental exposure testing evaluates biomarkers associated with compounds such as:MycotoxinsHeavy metals (in some panels)Industrial chemicalsThese tests may help characterize exposure patterns, though interpretation can be complex due to variability in exposure timing, metabolism, and elimination. Clinical relevance should be assessed cautiously and within the broader evidence base (Warth, 2013; Owolabi, 2024).Clinical TakeawaysOrganic acids testing may offer a systems-level view of metabolism and support pattern recognition when interpreted in context (Gallagher, 2018).Environmental testing may help identify exposure patterns, though clinical actionability varies (Warth, 2013; Owolabi, 2024).<span style="background-color
