GI Effects® Comprehensive Profile - 1 day

GI Effects is a comprehensive stool test that evaluates digestive function, intestinal inflammation, and the gut microbiome using PCR, culture, and microscopy. It may be useful for those exploring persistent bloating, changes in bowel habits, abdominal discomfort, food-related digestive symptoms, or other ongoing GI concerns. The panel provides a broad assessment of microbial balance, digestive capacity, inflammatory markers, and key biomarkers that can help identify patterns involving dysbiosis, maldigestion, and intestinal function. This is self-directed testing; interpretation and individualized recommendations are not included.
