Stool pH Test - Hindustan Laboratory

About the Stool pH Test

The Stool pH Test measures the acidity or alkalinity (pH level) of a stool sample to evaluate digestive health. The pH of stool reflects the balance of acids and bases in the digestive tract, influenced by diet, gut bacteria, and digestion processes. Normal stool pH ranges from 6.0 to 7.2, with deviations indicating potential digestive disorders.

An acidic stool (pH < 6.0) may suggest carbohydrate malabsorption, lactose intolerance, or excessive fermentation by gut bacteria. An alkaline stool (pH > 7.2) can indicate fat malabsorption, bile acid issues, or certain infections. This test helps diagnose conditions like lactose intolerance, celiac disease, pancreatic insufficiency, or inflammatory bowel disease.

At Hindustan Laboratory, we provide accurate Stool pH Testing to support the diagnosis and management of digestive health issues.

Stool pH Test at Hindustan Laboratory

The Stool pH Test is a non-invasive diagnostic procedure that analyzes the pH level of a stool sample. It is performed using precise laboratory techniques to provide reliable results, aiding in the assessment of gastrointestinal function.

Why Get Tested?

You may need a Stool pH Test if you experience:

Chronic diarrhea, bloating, or abdominal pain.
Suspected lactose intolerance or carbohydrate malabsorption.
Symptoms of fat malabsorption (e.g., greasy, foul-smelling stools).
Diagnosed or suspected conditions like celiac disease, Crohn’s disease, or pancreatic insufficiency.
Unexplained weight loss or nutritional deficiencies.

The test helps identify the cause of digestive symptoms and guides treatment plans.

Test Procedure

The Stool pH Test involves:

Sample Collection: You collect a small stool sample in a clean, sterile container provided by the laboratory. Instructions ensure proper collection to avoid contamination (e.g., avoid mixing with urine or water).
Preparation: No fasting is required. Avoid medications like antacids, laxatives, or antibiotics for 48 hours before the test, as they may alter stool pH. Inform your doctor about your diet and medications.
Testing Method: The stool sample is analyzed using a pH meter or pH indicator strips in a controlled laboratory setting. The pH level is measured and reported, often alongside other stool tests (e.g., fecal fat, reducing substances) for comprehensive evaluation.

The test is non-invasive and carries no risks beyond minor discomfort during sample collection. Results are typically available within 1–2 days.

Test Results

Stool pH results are interpreted as follows:

Normal: pH 6.0–7.2, indicating healthy digestion and gut flora balance.
Acidic: pH < 6.0, suggesting carbohydrate malabsorption (e.g., lactose intolerance), excessive fermentation, or disaccharidase deficiency.
Alkaline: pH > 7.2, indicating fat malabsorption, bile acid deficiency, or infections like cholera.

Abnormal results may prompt additional tests (e.g., stool culture, fecal fat test) to pinpoint the cause. Consult your doctor to interpret results in the context of symptoms and medical history.
