About this webinar
As interest in gut microbiome testing continues to grow, clinicians are faced with an important question: which stool tests provide clinically actionable information? This session examines the current landscape of gut microbiome testing, including recent concerns surrounding direct-to-consumer testing, and explores the characteristics that distinguish analytically validated clinical testing from research or wellness-oriented approaches.
Using Doctor's Data's GI360™ as a clinical example, Dr. Julia Malkowski will review the scientific and methodological foundations of comprehensive stool testing, including microbiome analysis, pathogen detection, culture, PCR, microscopy, stool chemistry, and susceptibility testing. Attendees will learn a practical framework for evaluating stool testing platforms and interpreting results within the context of patient care.
The session concludes with two clinical case studies demonstrating how integrating microbiome, culture, immune, and functional markers can support individualized treatment planning for patients with persistent gastrointestinal symptoms despite otherwise unremarkable conventional workups.
Key takeaways
- Evaluate how concerns surrounding direct-to-consumer microbiome testing compare with clinically validated laboratory testing, and learn four key questions to evaluate any stool testing platform.
- Explore the technologies that comprise the GI360™ platform, including validated PCR, culture with MALDI-TOF identification, microscopy, stool chemistry, and direct antimicrobial susceptibility testing.
- Learn how to interpret key report elements—including dysbiosis and diversity scoring, inflammatory markers, digestion and absorption markers, mucosal immune markers, and pathogen findings—to support clinical decision-making.
- Review clinical scenarios in which comprehensive stool testing may be appropriate, including persistent, relapsing, post-infectious, and systemic presentations.
- Apply a structured interpretation framework through two real-world case studies demonstrating how integrated microbiome, culture, chemistry, and immune findings informed individualized treatment strategies.
