The stool culture is a test that detects and identifies bacteria that cause infections of the lower digestive tract. The test distinguishes between the types of bacteria that cause disease and the types that are normally found in the digestive tract (normal flora).
A test for fecal occult blood looks for blood in your poop, or feces. It can be a sign of a problem in your digestive system, such as a growth, or polyp, or cancer in the colon or rectum. If the results show that there is blood (whether you can see it or not), it’s important for your doctor to find the source of bleeding to diagnose and treat the problem.
Your doctor can order a stool ova and parasites (O&P) test to check for parasites and their eggs in your stool, or feces. It’s a relatively easy and common test. Your doctor will likely ask you to collect a sample of your stool at home. Then the sample will be delivered to a laboratory for testing.
Salmonella and shigella represent two of the most common bacterial causes of diarrhea. If other common causes of diarrhea are suspected, they must be ordered individually. For many patients, the cause of gastrointestinal infection is not identified.
