The GI Effects Digestive Function & Microbiome Test is a comprehensive stool analysis designed to provide detailed insight into digestive health, gut function and the balance of the gut microbiome.
This advanced laboratory test evaluates how effectively you digest and absorb nutrients, assesses markers of inflammation and immune activity, and analyses the balance of beneficial and potentially harmful microorganisms within the digestive tract.
It can help identify underlying imbalances that may be contributing to digestive symptoms and support the development of a personalised nutrition and lifestyle programme.
