For example, norovirus and campylobacter are common causes of infectious diarrheal disease. Stool samples can also be used to detect occult blood in the gastrointestinal tract, indicating possible bleeding.
Stool samples
Stool samples are most commonly used to examine the causes of infectious bacterial and viral diarrhea.
For different types of stool samples collected at home, you will always receive separate instructions and materials from the laboratory. Follow the patient instructions carefully. In most cases, no special preparation is required before giving a stool sample.
Provide the sample as described in the patient instructions. Transfer the sample into the specimen container provided by the laboratory as soon as possible. The container does not need to be filled completely. Make sure no sample gets on the outside of the container. It is important to close the lid tightly. After giving the sample, wash your hands thoroughly with soap.
If the sample is collected at home, it must be stored and delivered to the laboratory according to the instructions. If you cannot take the sample to the laboratory immediately, store it in the refrigerator in a tightly sealed plastic bag. Giving a stool sample does not require follow-up and does not restrict normal daily activities.
Your attending physician will inform you of the results and how treatment will proceed. Contact your care unit if you do not have a scheduled appointment or call time.
There are no risks associated with giving a stool sample.
