US BioTek GI Profile – Standard is a comprehensive stool analysis designed to evaluate key markers of gastrointestinal health, microbial balance, and digestive function. This test assesses the presence of beneficial and pathogenic bacteria, yeast, and parasites, while also measuring inflammation, digestion, absorption, and immune activity within the gut.

With insights into gut ecology and intestinal integrity, the GI Profile helps uncover hidden imbalances contributing to chronic symptoms such as bloating, constipation, diarrhea, fatigue, and food sensitivities. It’s an essential tool for personalized gut healing protocols in functional and integrative medicine.
