Proper Storage of Blood Specimens: Guidelines for Healthcare Professionals

Summary

• Proper storage of blood specimens is crucial to ensure accurate laboratory Test Results.
• Healthcare professionals must follow guidelines to maintain the integrity of blood samples during storage.
• Temperature control, labeling, and secure packaging are key components of proper blood specimen storage.

Introduction

Medical laboratory testing plays a vital role in diagnosing and treating patients. One of the key components of laboratory testing is the proper collection and storage of blood specimens. Healthcare professionals, particularly phlebotomists, are responsible for collecting blood samples and ensuring they are stored correctly before being transported to the laboratory for analysis. In this article, we will discuss how healthcare professionals should properly store collected blood specimens prior to transport to the laboratory in the United States.

Temperature Control

One of the most important factors in storing blood specimens is temperature control. Improper storage temperatures can lead to hemolysis, clotting, or bacterial contamination, which can affect the accuracy of laboratory Test Results. Healthcare professionals should follow these guidelines for temperature control:

1. Store blood specimens at the appropriate temperature recommended by the laboratory. Different tests may require different storage temperatures, so it is essential to read and follow the instructions carefully.
2. Ensure that the storage area is maintained at a consistent temperature. Fluctuations in temperature can also affect the integrity of blood samples.
3. Use refrigeration or freezer units specifically designed for storing blood specimens. These units should be regularly monitored and calibrated to ensure they are functioning correctly.

Labeling

Proper labeling of blood specimens is essential for accurate identification and tracking. Healthcare professionals should follow these guidelines for labeling blood samples:

1. Label each blood specimen with the patient's name, date of birth, and medical record number. This information is critical for ensuring that the correct Test Results are linked to the correct patient.
2. Include the date and time of collection on each blood specimen. This information helps the laboratory determine the stability of the sample and prioritize tests that have time-sensitive requirements.
3. Use barcode labels or unique identifiers to further enhance the accuracy and efficiency of specimen tracking. This can help prevent mix-ups and ensure that each specimen is processed correctly.

Secure Packaging

Once blood specimens are collected and labeled, they must be securely packaged to prevent leakage, breakage, or contamination during transport. Healthcare professionals should follow these guidelines for secure packaging:

1. Use leak-proof and break-resistant containers to transport blood specimens. These containers should be specifically designed for medical specimens and compliant with transportation Regulations.
2. Place absorbent material, such as cotton or gauze, around the blood specimen to prevent leakage in case of breakage. This extra precaution can help protect both the specimen and healthcare workers handling the package.
3. Seal the container with a secure lid or cap to prevent contamination. Some containers may also require secondary packaging, such as a biohazard bag, for additional protection during transport.

Conclusion

Proper storage of blood specimens is essential for maintaining the integrity of laboratory Test Results. Healthcare professionals, particularly phlebotomists, play a critical role in ensuring that blood samples are collected, stored, and transported correctly. By following guidelines for temperature control, labeling, and secure packaging, healthcare professionals can help prevent errors and ensure accurate Test Results for patient care.
