Digestive health plays a crucial role in overall well-being, especially for infants, children, and individuals experiencing persistent gastrointestinal symptoms. When problems like chronic diarrhea, abdominal discomfort, poor weight gain, or suspected carbohydrate intolerance arise, doctors often recommend specialized stool tests to identify the root cause. One such important investigation is the pH & Reducing Substances (Stool) test, which helps assess how well the body digests and absorbs carbohydrates.
The pH & Reducing Substances (Stool) test at Alnoor Diagnostic Centre is a reliable diagnostic tool used to detect malabsorption issues, particularly lactose intolerance and other carbohydrate digestion disorders. Alnoor Diagnostic Centre is known for its accurate testing standards, modern laboratory equipment, and experienced technical staff, making it a trusted choice for patients across Pakistan.
This test is commonly advised for pediatric patients but is equally useful for adults with unexplained digestive complaints. With an affordable price and convenient booking options, Alnoor Diagnostic Centre ensures quality diagnostics that support timely medical decisions and better patient outcomes.
What is pH & Reducing Substances (Stool) Test?
The pH & Reducing Substances (Stool) test is a laboratory examination of a stool sample to evaluate carbohydrate digestion and absorption in the gastrointestinal tract.
What does the test measure?
- Stool pH: Indicates the acidity or alkalinity of the stool. Acidic stool may suggest carbohydrate malabsorption.
- Reducing substances: Detects the presence of unabsorbed sugars (such as lactose, glucose, or fructose) in the stool.
When do doctors recommend this test?
Doctors recommend this test when a patient shows signs of:
- Lactose intolerance
- Carbohydrate malabsorption
- Chronic or unexplained diarrhea
- Failure to thrive in infants
- Suspected intestinal enzyme deficiencies
Medical uses
The test helps diagnose:
- Lactase deficiency
- Congenital carbohydrate intolerance
- Secondary malabsorption due to infections or intestinal damage
The pH & Reducing Substances (Stool) test at Alnoor Diagnostic Centre provides valuable insights into digestive efficiency, especially in young children.
Why is pH & Reducing Substances (Stool) Test Important?
This test is important because undiagnosed carbohydrate malabsorption can lead to long-term health issues, especially in growing children.
Key reasons this test matters:
- Identifies hidden causes of chronic diarrhea
- Helps diagnose lactose intolerance early
- Prevents nutritional deficiencies
- Guides dietary modifications
- Supports accurate pediatric diagnosis
An acidic stool pH combined with positive reducing substances often indicates that sugars are not being properly digested or absorbed. Early detection through the Alnoor Diagnostic Centre pH & Reducing Substances (Stool) test allows doctors to manage symptoms effectively and prevent complications.
When Should You Get a pH & Reducing Substances (Stool) Test?
You may need this test if a doctor suspects digestive or absorption issues.

pH & Reducing Substances (Stool) Report & Normal Values

Normal Values Table
| Test Parameter | Normal Range | Interpretation |
| Stool pH | 7.0 – 7.5 | Normal digestion |
| Reducing Substances | Negative | Normal carbohydrate absorption |
Report interpretation:
- Low stool pH (<6.0): Suggests carbohydrate malabsorption
- Positive reducing substances: Indicates unabsorbed sugars in stool
Only a doctor can correlate these findings with symptoms and medical history to make a diagnosis.
