A stool test, also known as a fecal test, involves analyzing a sample of your bowel movement to identify conditions affecting the digestive system. This common diagnostic tool helps healthcare providers detect abnormalities that may indicate underlying health concerns.
Preparing for Your Stool Sample Collection
Before collecting a stool sample, always follow your healthcare provider’s specific instructions, as protocols can differ depending on the particular test ordered. Your doctor may advise adjustments to certain medications, such as avoiding antacids, laxatives, antibiotics, or iron supplements, which could interfere with test results. It is important to consult with your doctor before discontinuing any prescribed medication.
Dietary considerations might also be necessary; for instance, some tests, like those for fecal occult blood, may require avoiding red meat to prevent false positives. Before beginning the collection process, gather all necessary supplies, which typically include a specialized collection kit provided by the laboratory or doctor, disposable gloves, and a clean container or collection device.
Step-by-Step Stool Sample Collection
Begin the collection process by washing your hands thoroughly with soap and water and putting on disposable gloves to maintain hygiene and prevent contamination. To collect the sample without contamination from urine or toilet water, use a specialized device such as a “hat” placed under the toilet seat, plastic wrap draped across the toilet rim, or specialized collection paper. It is important to urinate before the bowel movement to avoid contaminating the sample.
After a bowel movement, use the designated scoop, spatula, or applicator provided in the kit to transfer the required amount of stool into the collection container. The amount needed is typically indicated by a fill line on the container or by specific instructions, such as 2 to 3 small scoopfuls. Once the sample is transferred, securely close the container to prevent any leaks. Clearly label the container with your full name, date of birth, and the date and time of collection as specified by the laboratory. After the sample is secured and labeled, dispose of all used materials properly and wash your hands again.
Storing and Transporting Your Sample
Once the stool sample is collected and securely sealed, proper storage is necessary to maintain its integrity for testing. Depending on the specific test, the sample may need to be refrigerated immediately, while others can remain at room temperature. Always follow the laboratory’s instructions regarding storage conditions to prevent sample degradation.
Timely submission of the sample is also important for accurate results. Most laboratories recommend delivering the sample within 24 to 72 hours of collection, or as otherwise instructed by your healthcare provider. When transporting the sample, ensure it is safely packaged in a leak-proof bag and protected from extreme temperatures. Your healthcare provider will typically discuss the test results with you after the laboratory analysis is complete.
