Stool culture; Culture - stool; Gastroenteritis fecal culture
A fecal culture is a lab test to find organisms in the stool (feces) that can cause gastrointestinal symptoms and disease.
A stool sample is needed.
There are many ways to collect the sample.
You can collect the sample:
Do not mix urine, water, or toilet tissue with the sample.
For children wearing diapers:
Return the sample to the laboratory as soon as possible. Do not include toilet paper or urine in the specimen.
In the lab, a technician places a sample of the specimen in a special dish. The dish is then filled with a gel that boosts the growth of bacteria or other germs. If there is growth, the germs are identified. The lab technician may also do more tests to determine the best treatment.
You will get a collection container for the stool specimen.
There is no discomfort.
The test is performed when your health care provider suspects that you may have a gastrointestinal infection. It may be done if you have severe diarrhea that does not go away or that keeps coming back.
There are no abnormal bacteria or other organisms in the sample.
Abnormal results may mean you have an intestinal infection. Talk to your provider about the meaning of your specific test results.
There are no risks.
Often other stool tests are done in addition to the culture, such as:
