What is this test?
This laboratory test is performed on a stool sample to detect the presence of pathogenic bacteria present in the stool. This test helps in identifying the cause of lower digestive tract infections. It also helps in guiding the appropriate treatment.
Why is this test performed?
This test is performed:
- To detect the presence of pathogenic bacteria in the stool such as Salmonella, Shigella, and vibrio species

- Avoid consuming uncooked vegetables
- Avoid unpasteurized dairy products
- Why do we need to submit the sample quickly?
You need to submit your stool sample in the laboratory as soon as possible because:
