A stool test can diagnose abnormalities such as infection, parasites, or colon cancer. Samples are usually collected at home and sent to a lab for testing. Results can prompt further medical attention and treatment.
A stool test is a medical procedure in which a small stool sample is collected and tested for abnormalities such as infection or the presence of blood. Intestinal parasites, colon cancer or lactose intolerance can often be diagnosed as a result of a stool test. In most cases, the sample is collected at home and then transported to the doctor’s office or laboratory, although occasionally the sample may be taken by a member of the medical staff. If the sample is to be collected at home, medical personnel will provide detailed instructions on how to properly collect and store the sample. Any questions or concerns about the stool test should be discussed with the supervising physician.
In many cases, a doctor will order a stool test if a person is suspected to have food poisoning. If the stool sample contains certain types of bacteria and can be traced back to a particular food, the food can be removed from circulation so other people don’t get sick. Parasitic infections can also be diagnosed through the use of a stool test. Once the type of parasite has been identified, appropriate treatment can begin.
If a stool test reveals blood in the stool, it could indicate the presence of a tear in the rectal area, damage involving the stomach or intestines, or the presence of colon cancer. Further tests, such as ultrasounds or biopsies, may be performed based on the results of this test. Some stool tests, especially those designed to test for colon cancer, can often be done at home and shipped to an outside lab. The results are sent back to the patient within a few days or weeks. Any abnormal findings should prompt a follow-up visit with a doctor.
Home-collected stool samples are usually placed in plastic containers provided by the ordering physician. The samples are then delivered to the doctor’s office or laboratory as directed by the medical staff. If it is not possible to deposit the sample immediately after collection, it should be refrigerated until ready to be delivered. In cases where your doctor gives you specific instructions about collecting and storing samples for stool testing, they should be followed carefully. After the doctor receives the test results, an individualized treatment plan can be developed based on the patient’s specific needs.
