Reducing Substances -Stool

Reducing Substances - Stool Test

The Reducing Substances - Stool Test is a specialized laboratory test used to detect the presence of unabsorbed sugars (reducing sugars) in stool. This test helps evaluate carbohydrate malabsorption disorders, digestive enzyme deficiencies, and certain gastrointestinal conditions that affect the body's ability to properly digest and absorb sugars.

Normally, carbohydrates are broken down and absorbed in the small intestine. When digestion or absorption is impaired, undigested sugars pass into the stool. Detecting reducing substances helps doctors identify conditions such as lactose intolerance, congenital enzyme deficiencies, intestinal malabsorption, and gastrointestinal infections affecting sugar absorption.

This test is commonly recommended for infants, children, and adults with persistent digestive symptoms.
