How To Store Blood Collection Tubes For Drug Level Testing

When it comes to drug level testing, the accuracy of the results is crucial. One important factor that can impact the accuracy of these tests is how blood collection tubes are stored prior to testing. Proper storage of blood collection tubes is essential to ensure reliable results. In this article, we will discuss the best practices for storing blood collection tubes for drug level testing.

Importance of Proper Blood Collection Tube Storage

Before we dive into the specifics of how to store blood collection tubes, let's first discuss why proper storage is so important. Blood collection tubes typically contain additives that are designed to preserve the integrity of the blood sample until it can be tested. These additives can be sensitive to temperature, light, and other environmental factors. Improper storage can lead to changes in the composition of the blood sample, which can in turn impact the accuracy of the drug level test results.

Best Practices for Storing Blood Collection Tubes

Temperature

One of the most important factors to consider when storing blood collection tubes is temperature. It is crucial to store blood collection tubes at the appropriate temperature to prevent degradation of the sample. The ideal temperature for storing blood collection tubes is typically between 2-8 degrees Celsius (36-46 degrees Fahrenheit).

It is recommended to store blood collection tubes in a refrigerator or in a temperature-controlled environment to maintain the desired temperature. Avoid storing blood collection tubes in areas that are exposed to extreme temperatures or fluctuations in temperature, as this can compromise the integrity of the sample.

Light Exposure

In addition to temperature, light exposure can also impact the stability of blood collection tubes. Some additives in blood collection tubes are sensitive to light and can degrade when exposed to light for extended periods of time. It is important to store blood collection tubes in a dark or opaque container to protect them from light exposure.

If you are using clear blood collection tubes, consider wrapping them in aluminum foil or storing them in a light-blocking container to minimize light exposure. This can help preserve the integrity of the blood sample and ensure accurate drug level test results.

Storage Duration

Another important consideration when storing blood collection tubes is the duration of storage. It is recommended to test blood samples as soon as possible after collection to minimize the risk of sample degradation. If immediate testing is not possible, store the blood collection tubes in the refrigerator and test them within the recommended timeframe specified by the testing facility.

Do not store blood collection tubes for longer than the recommended duration, as this can lead to changes in the composition of the sample and affect the accuracy of the test results. Be sure to check the storage guidelines provided by the testing facility to ensure that you are following the proper storage protocols.

Conclusion

Proper storage of blood collection tubes is essential to ensure the accuracy and reliability of drug level test results. By following the best practices outlined in this article, you can help preserve the integrity of the blood sample and minimize the risk of sample degradation. Remember to store blood collection tubes at the appropriate temperature, protect them from light exposure, and test them within the recommended storage duration. By taking these precautions, you can help ensure that your drug level test results are accurate and reliable.
