About this test
Key Benefits
Assess Digestive Function: Evaluate how efficiently your body breaks down and absorbs nutrients.
Measure Digestive Residues: Analyze fat, protein, sugar, and water content in stool.
Simple At-Home Testing: Collect your stool sample easily at home.
Detailed Digital Results: Access your laboratory results online after analysis.
Gut Health Insights: Gain insight into digestion, absorption, and gastrointestinal balance.
What This Test Measures
This test measures several digestive residues in stool, including:
Fat Residues – Evaluates fat digestion and absorption.
Nitrogen Residues – Provides insight into protein breakdown and digestion.
Sugar Residues – Assesses carbohydrate digestion efficiency.
Water Content – Reflects stool consistency and digestive balance.
Elevated levels of digestive residues may indicate impaired digestion, malabsorption, enzyme insufficiency, or gastrointestinal imbalance.
About Digestion and Gut Function
Efficient digestion is essential for proper nutrient absorption and overall health. The digestive system relies on enzymes, stomach acid, bile production, and gut function to break down food and absorb nutrients effectively.
When digestion or absorption is impaired, nutrients may remain in the stool rather than being fully utilized by the body. Measuring digestive residues may provide additional insight into digestive efficiency and gastrointestinal health.

Biomarkers included
- Quantitative Determination of Nitrogen: The quantitative determination of nitrogen (N) is a laboratory test that measures nitrogen levels in bodily excretions, typically urine or feces, to assess protein digestion and absorption. This test is essential for evaluating nutritional status, especially in clinical settings where protein-energy malnutrition or imbalances may be a concern. It provides key insights into metabolic functions rela
- Quantitative Determination of Water: The stool water content analysis is a test that measures the amount of water present in feces. This assessment is important for diagnosing conditions related to abnormal water absorption or secretion in the gastrointestinal tract. It helps identify causes of diarrhea, which may result from infections, inflammatory bowel diseases (IBD), irritable bowel syndrome (IBS), or malabsorption syndromes, wh
- Quantitative Determination of Sugar: The quantitative stool sugar test is a diagnostic tool that measures the amount of specific sugars in stool to assess carbohydrate malabsorption. It helps identify conditions like lactose intolerance, fructose intolerance, and other disorders affecting sugar digestion and absorption. By detecting undigested sugars such as lactose, fructose, or sorbitol in the stool, this test aids healthcare provi
- Quantitative Determination of Fat: The stool fat test is a diagnostic measure that quantifies the amount of fat excreted in stool samples. It is used to assess fat absorption and to detect malabsorption syndromes. Elevated fat levels in stool, known as steatorrhea, can indicate digestive or absorption issues within the gastrointestinal tract. This test aids in diagnosing conditions such as pancreatic insufficiency, cystic fibrosis,
How to prepare
Maintain a normal diet containing fats, proteins, and carbohydrates for 3 days prior to collection to ensure accurate residue measurement.
Frequently asked questions
How does it work? / When do I get my results?
1. Order and receive your kit. 2. Perform the test. 3. Send a sample at the beginning of the week (to avoid delays). 4. Results digitally in 10–15 business days.
What does it mean if my residue levels are high?
Elevated levels of fat, protein (nitrogen), or sugar in your stool suggest that your body is not effectively breaking down or absorbing these nutrients. This can be caused by various factors including insufficient digestive enzymes, low stomach acid, rapid transit time, or damage to the intestinal lining where absorption occurs.
Do I need to follow a special diet before the test?
No specific fasting is required, but it is recommended to maintain your usual diet in the days leading up to the test. This ensures the results reflect how your body typically processes the foods you normally eat.
