A stool specimen is a sample of feces that is collected and examined to detect any abnormalities in the digestive system. It is commonly used to diagnose various gastrointestinal disorders, such as infections, inflammation, or cancer. However, the accuracy of the test results depends on the quality of the specimen, which can be compromised by various factors. In this blog post, we will discuss what can ruin a stool specimen if it is included.
1. Contamination: The first and most common cause of a ruined stool specimen is contamination. Feces can easily get contaminated by urine, toilet paper, or cleaning agents used in the toilet. These contaminants can interfere with the test results and make it difficult to identify any abnormalities in the stool. To avoid contamination, it is crucial to follow the collection instructions carefully, which usually involve using a clean container and avoiding contact with any foreign substances.
2. Inadequate specimen size: Another factor that can affect the accuracy of the stool specimen is its size. A small or insufficient sample may not contain enough material to detect any abnormalities. In contrast, a large sample can dilute the concentration of the fecal matter, making it difficult to identify any specific pathogens or bacteria. Therefore, it is essential to collect a sufficient amount of stool, usually about the size of a walnut, to ensure accurate test results.
3. Improper storage: Stool specimens must be stored properly to prevent any changes in the composition or structure of the fecal matter. Exposure to air, heat, or moisture can alter the pH level, bacteria growth, or other chemical reactions in the stool, leading to inaccurate test results. Therefore, it is vital to store the specimen in a sealed container, preferably in a cool and dark place, until it is transported to the laboratory.
4. Medications and dietary supplements: Certain medications and dietary supplements can affect the composition of the stool, making it difficult to identify any abnormalities. For example, antibiotics can alter the bacterial flora in the gut, while iron supplements can change the color of the stool. Therefore, it is essential to inform your healthcare provider of any medications or supplements you are taking before collecting the stool specimen.
5. Delayed transport: Finally, delayed transport of the stool specimen can also affect the test results. The longer the specimen is left at room temperature, the greater the chances of bacterial growth and decomposition, which can alter the composition of the stool. Therefore, it is crucial to transport the specimen to the laboratory as soon as possible, preferably within 24 hours, to ensure accurate test results.
In conclusion, a stool specimen can provide valuable information about the health of the digestive system, but its accuracy depends on various factors that can ruin the sample if not included. To ensure accurate test results, it is essential to follow the collection instructions carefully, store the specimen properly, avoid medications and supplements that can affect the stool composition, and transport the specimen to the laboratory promptly. By doing so, you can help your healthcare provider diagnose any gastrointestinal disorders and provide appropriate treatment.
