Storage And Handling Of Blood Samples In Citrate Tubes: Factors, Best Practices, And Conclusion

Summary

• Blood samples collected in citrate tubes can be stored for up to 24 hours at room temperature.
• For longer storage, the samples should be refrigerated at 2-8 degrees Celsius.
• Proper storage and handling of blood samples in citrate tubes are crucial to ensure accurate Test Results.

Introduction

When it comes to collecting blood samples for laboratory testing, proper handling and storage are essential to ensure accurate results. One common method of collecting blood samples is using citrate tubes, which contain citrate as an anticoagulant. But how long can blood samples collected in citrate tubes be stored before they are no longer viable for testing? In this article, we will explore the factors that determine the storage time of blood samples in citrate tubes and the best practices for handling them.

Factors Affecting Storage Time

Several factors can affect the storage time of blood samples collected in citrate tubes:

Temperature

One of the most critical factors affecting the storage time of blood samples is the temperature at which they are stored. At room temperature (around 25 degrees Celsius), blood samples collected in citrate tubes can be stored for up to 24 hours. However, for longer storage periods, it is recommended to refrigerate the samples at 2-8 degrees Celsius.

Hemolysis

Hemolysis, the breakdown of red blood cells, can occur if blood samples are stored or handled improperly. Hemolyzed samples can affect the accuracy of Test Results and may need to be recollected. Proper handling and storage of blood samples in citrate tubes can help prevent hemolysis.

Contamination

Contamination of blood samples can also affect their storage time. It is essential to ensure that citrate tubes are properly labeled and sealed to prevent contamination. Contaminated samples may need to be discarded, leading to the need for recollection.

Best Practices for Handling Blood Samples in Citrate Tubes

To ensure the integrity of blood samples collected in citrate tubes, it is essential to follow best practices for handling and storage:

1. Label each citrate tube with the patient's name, date, and time of collection.
2. Ensure that the citrate tubes are properly sealed to prevent contamination.
3. Store the samples in an upright position to prevent leakage.
4. Transport the samples to the laboratory promptly for processing.
5. If refrigeration is required, store the samples at 2-8 degrees Celsius.

Conclusion

Proper handling and storage of blood samples collected in citrate tubes are crucial to ensure accurate Test Results. By following best practices for handling blood samples, healthcare professionals can minimize the risk of hemolysis, contamination, and other factors that can affect the integrity of the samples. Remember that blood samples collected in citrate tubes can be stored for up to 24 hours at room temperature, but for longer storage periods, refrigeration is recommended. By following these guidelines, Healthcare Providers can ensure the reliability of laboratory Test Results and provide quality care to their patients.
