Proper Storage Requirements for Stool Specimens: Maintaining Integrity for Accurate Test Results

Summary

• Proper storage of stool specimens is crucial to ensure accurate Test Results
• Stool specimens should be stored in a sealed container at room temperature or refrigerated, depending on the test being performed
• Following the specific storage guidelines provided by the healthcare provider is essential to maintain the integrity of the specimen

Introduction

When it comes to collecting stool specimens for medical testing, proper handling and storage are essential to ensure accurate results. Stool specimens can provide valuable information about a person's digestive health, infections, and other underlying conditions. However, if not stored correctly, the integrity of the specimen may be compromised, leading to inaccurate Test Results. In this article, we will explore the specific storage requirements for stool specimens after being collected in the container.

Why are storage requirements important?

Stool specimens contain bacteria, viruses, and other microorganisms that can quickly degrade if not stored properly. Proper storage helps maintain the integrity of the specimen and ensures that the Test Results are accurate. Without following the necessary storage guidelines, the specimen may become contaminated, leading to false-positive or false-negative results. Therefore, it is crucial to adhere to the specific storage requirements provided by the healthcare provider.

Specific storage requirements for stool specimens

Room temperature storage

1. Some stool specimens can be stored at room temperature before being processed for testing. However, it is essential to seal the container tightly to prevent any leakage or contamination.
2. Stool samples collected for routine tests, such as fecal occult blood test (FOBT) or fecal immunochemical test (FIT), can typically be stored at room temperature for a certain period before testing.
3. It is important to check with the healthcare provider or laboratory for specific instructions on how long the specimen can be stored at room temperature before testing.

Refrigerated storage

1. For some stool tests, such as stool cultures or parasitology exams, the specimen may need to be stored in the refrigerator to preserve the microorganisms for testing.
2. Stool specimens collected for testing that requires refrigeration should be placed in a sealed container and stored in the refrigerator at the recommended temperature.
3. The recommended temperature for refrigerated storage of stool specimens is typically around 2-8 degrees Celsius (36-46 degrees Fahrenheit).
4. It is essential to follow the specific storage guidelines provided by the healthcare provider or laboratory to maintain the integrity of the specimen.

Freezing

1. While most stool specimens do not require freezing, there may be specific tests that require the specimen to be frozen to preserve certain components for testing.
2. If freezing stool specimens is necessary, it is crucial to follow the instructions provided by the healthcare provider or laboratory to ensure the specimen remains viable for testing.
3. Properly label the container with the patient's information and the date and time the sample was collected before freezing.
4. Thaw frozen stool specimens according to the instructions provided before testing to prevent any damage to the sample.

Conclusion

Proper storage of stool specimens after being collected in the container is essential to maintain the integrity of the sample and ensure accurate Test Results. Whether the specimen needs to be stored at room temperature, refrigerated, or frozen depends on the type of test being performed. It is crucial to follow the specific storage requirements provided by the healthcare provider or laboratory to prevent contamination and maintain the quality of the specimen. By adhering to the recommended storage guidelines, healthcare professionals can ensure that the Test Results are accurate and reliable.
