Stool pH Test: A laboratory analysis that measures the acidity or alkalinity of a stool sample. This test can provide insights into gastrointestinal health and the presence of certain digestive disorders.
Purpose: The stool pH test is primarily used to assess malabsorption disorders, such as lactose intolerance or carbohydrate malabsorption. Abnormal pH levels may indicate the presence of undigested food in the stool.
Sample Collection: A small sample of stool is collected in a sterile container. It is important to follow proper collection guidelines to ensure accurate results.
Normal Range: Normal stool pH typically ranges from 6.5 to 7.5, indicating a balanced environment in the intestines. Values outside this range can suggest underlying issues.
Interpretation:
Low pH (acidic): A stool pH below 6.0 may indicate carbohydrate malabsorption or the presence of certain types of infections.
High pH (alkaline): A pH above 7.5 can suggest a malabsorption condition or an overgrowth of certain bacteria in the intestines.
Clinical Relevance: Measuring stool pH is a valuable diagnostic tool in evaluating gastrointestinal disorders, guiding treatment decisions, and monitoring the effectiveness of dietary changes or therapies for malabsorption issues.
