Collecting a stool sample is a crucial process for diagnosing a variety of gastrointestinal and systemic conditions. To ensure accurate results, it is essential to use the appropriate container. This article explores the features, types, and best practices for choosing the best container for stool sample collection.

 

Stool tests analyze samples of feces (also known as bowel motions). Depending on the purpose of the test, stool samples can be examined in the laboratory using various methods. These tests are sometimes referred to as fecal tests.

 

There are many reasons why you might be advised to have a stool test, including:

 

To identify the cause of an infection

To check for inflammatory bowel disease

To determine if you are absorbing food properly

To screen for bowel cancer

 

Stool samples are used to diagnose infections, digestive problems, and even cancers. An improperly collected or stored sample can lead to incorrect diagnoses, delays in treatment, and the need for repeat testing. Thus, selecting the right container is the first step in ensuring the sample remains uncontaminated and suitable for analysis.

 

 

An immunochemical fecal occult blood test (iFOBT) is used for bowel cancer screening. It tests healthy individuals for blood in their feces that may be indicative of bowel cancer. The test can detect tiny, invisible amounts of blood, aiming to find cancers early.

 

If the test detects blood in your feces, you will need additional testing to determine the cause, which is not always cancer.

 

Stool samples for iFOBTs can be easily collected in the privacy of your own home. You will receive a free kit in the mail with instructions as part of the National Bowel Cancer Screening Program. Once you have completed the test, you will need to mail the samples to the laboratory.

 

For stool tests related to infections, your doctor or pathology collector will provide you with sterile jars for sample collection. To collect your sample, use a clean plastic container lined with toilet paper to catch your feces, then transfer a portion into the sterile jars. Be careful not to contaminate the sample with urine or water. If you need to urinate, do so before collecting your stool sample.

 

Wear gloves and wash your hands thoroughly after handling the sample to avoid spreading any infection. Discard the remaining contents of the plastic container into the toilet.

 

You should take the sample to the laboratory as soon as possible. If immediate delivery is not possible, you may need to store the sample in the refrigerator until you can deliver it. Consult your doctor or pathology collector for specific instructions.

 

Sterility: The container must be sterile to prevent contamination from external bacteria or substances that could interfere with the test results.

Sealability: It should have a secure, leak-proof lid to prevent spills and contamination during transport.

Size: The container must be appropriately sized to collect an adequate sample without being excessively large.

Material: Containers are typically made from plastic, which is both lightweight and durable.

Ease of Use: The container should be easy to use, both for sample collection and for laboratory personnel during analysis.

 

Standard Screw Cap Containers: These are the most commonly used containers for stool samples. They are made from sterile plastic and have a secure screw on lid. They often come with a built in spoon attached to the lid for easy sample collection.

 

Commode Specimen Containers: These are large plastic containers designed to fit over the toilet bowl. They are particularly useful for patients who need to collect larger samples or have difficulty using smaller containers. Once the sample is collected, a portion can be transferred to a smaller screw cap container.

 

Collection Kits: Some healthcare providers offer stool collection kits that include a collection container, a transport container, and detailed instructions. These kits are designed to simplify the collection process and ensure the sample is handled correctly from start to finish.

 

Paraffin Wax Containers: These containers are less common but used in specific tests where the sample needs to be preserved for an extended period. The wax prevents degradation of the sample by sealing it from air and moisture.

 

Follow Instructions: Always follow the specific instructions provided by the healthcare provider or laboratory. Different tests may have unique requirements.

 

Avoid Contamination: Do not let urine or toilet water mix with the stool sample. Some patients use plastic wrap or special collection devices that fit over the toilet to avoid contamination.

 

Use the Provided Container: Always use the container provided by your healthcare provider. If no container is provided, use a clean, dry, and sterile container with a secure lid.

 

Label the Container: Clearly label the container with your name, date of birth, and the date and time of collection. This ensures the sample is correctly identified throughout the testing process.

 

Prompt Transport: Transport the sample to the laboratory as soon as possible. If there is a delay, store the sample in a refrigerator (but not the freezer) unless otherwise instructed.

 

Hygiene: Wash your hands thoroughly before and after collecting the sample to prevent the spread of pathogens.

 

Choosing the right container for stool sample collection is a critical step in the diagnostic process. Sterile, sealable, appropriately sized containers made from durable materials are essential. Standard screw cap containers are the most commonly used due to their convenience and reliability, but other options like commode specimen containers and specialized collection kits are also available.

 

Following best practices for stool sample collection, such as avoiding contamination, labeling the container correctly, and transporting the sample promptly, further ensures that the results will be accurate and useful for diagnosis. Always adhere to the instructions provided by your healthcare provider to achieve the best possible outcomes.

 

By understanding the importance of using the correct container and following proper collection procedures, patients can contribute significantly to the accuracy of their medical diagnoses, leading to more effective treatments and better health outcomes.
