About this service

Stool Analysis is a laboratory test used to evaluate the components of stool to detect a variety of health conditions. This test examines the sample for the presence of bacteria, parasites, fungi, or even invisible blood, helping diagnose infections, intestinal inflammation, and digestive disorders. The sample is usually collected by the patient and sent to the laboratory, where it is analyzed under precise conditions. Stool analysis is an important tool for investigating conditions such as persistent diarrhea, abdominal pain, or changes in bowel habits. The results help identify the underlying causes of symptoms, assisting doctors in making informed medical decisions and determining appropriate treatments. For accurate results, patients may be asked to avoid certain medications or supplements before the test. Stool analysis is a non-invasive and valuable method for a comprehensive assessment of digestive system health.

Test purpose

Bacteria: Helps identify bacterial infections such as Salmonella, Shigella, and Escherichia coli.
Parasites: Can detect parasites like Giardia lamblia and Entamoeba histolytica, indicating intestinal infections.
Fungi: May show the presence of fungi such as Candida in certain cases.
Occult (hidden) blood: Can reveal blood in the stool, which may indicate gastrointestinal bleeding or conditions like ulcers or cancer.
Undigested fats: Helps identify digestive problems, such as malabsorption of fats, including conditions like celiac disease.
pH levels: Stool acidity can indicate stool quality and help identify specific digestive issues.
Beneficial bacteria: Shows the balance between healthy and harmful gut bacteria.
Intestinal inflammation: Can reveal signs of inflammation or damage to the intestinal lining.
Indicators of other diseases: Such as celiac disease or Crohn’s disease.

Recommended groups

Individuals with intestinal symptoms: Such as persistent diarrhea, abdominal pain, cramps, or nausea.
Those with abnormal stool: Including changes in color or consistency, or the presence of blood or mucus in the stool.
Patients with a history of intestinal infections: For example, those diagnosed with infections like Salmonella or E. coli.
