Red Cell Selenium
The reducing substances test, also known as the fecal reducing substances test, is a diagnostic procedure used to identify the cause of diarrhea by detecting unabsorbed carbohydrates in the stool. This test is instrumental in distinguishing between osmotic and non-osmotic diarrhea, which are two different types of gastrointestinal disorders. It is particularly useful for diagnosing conditions such as disaccharidase deficiencies, like lactase deficiency, and monosaccharide malabsorption, which can lead to symptoms like frequent loose stools and abdominal discomfort. The test involves collecting a stool sample in a specific manner to ensure accuracy, using the Benedict's Copper Reduction Reaction to detect reducing substances. Results are interpreted based on the concentration of these substances, helping to identify issues like primary or secondary disaccharidase deficiency. Despite some limitations, such as sensitivity to oligosaccharides and potential drug interference, the test remains a valuable tool in diagnosing gastrointestinal disorders, especially in pediatric patients.

The reducing substances test is essential for diagnosing diarrhea causes by identifying unabsorbed carbohydrates in stool. It differentiates between osmotic and non-osmotic diarrhea, aiding in diagnosing conditions like:
- Disaccharidase Deficiencies: Lack of enzymes to break down disaccharides, e.g., lactase deficiency.
- Monosaccharide Malabsorption: Inability to absorb single sugars like glucose and fructose.
The test involves collecting a stool sample, using Benedict's Copper Reduction Reaction for analysis. Results indicate sugar absorption efficiency, guiding treatment. Despite limitations, it remains vital in diagnosing gastrointestinal disorders, especially in pediatrics.
The red cell selenium test is essential for evaluating selenium levels in red blood cells, crucial for various bodily functions. Key groups who should consider testing include:
- Individuals with symptoms of selenium deficiency, such as impaired immune function or thyroid issues.
- Those living in regions with low or high environmental selenium levels.
- Patients with chronic diseases potentially linked to selenium imbalance.
- Individuals experiencing symptoms of selenosis, like gastrointestinal upset or hair loss.
Accurate testing helps maintain optimal selenium levels, supporting overall health.
Understanding test results is crucial for effective diagnosis and treatment. The reducing substances test evaluates unabsorbed carbohydrates in stool, aiding in the diagnosis of gastrointestinal disorders. Here's how to interpret the results:
- Negative: Sugars are properly digested and absorbed.
- Normal: ≤0.25 g/dL (trace).
- Suspicious: >0.25 to 0.50 g/dL (grade 1).
- Abnormal: >0.50 g/dL (grade 2-4).
Elevated levels suggest issues like disaccharidase deficiencies or monosaccharide malabsorption, helping distinguish between osmotic and non-osmotic diarrhea.
