Precautions When Using Vacutainer Tubes: Check Expiration Date, Labeling, Order of Draw, Mixing, Handling, Storage, & Disposal

Summary

• Always check the expiration date of the vacutainer tubes before use.
• Ensure proper labeling of the tubes with patient information and test ordered.
• Follow correct handling and storage procedures to maintain the integrity of the specimens.

Introduction

Vacutainer tubes are widely used in healthcare settings for blood collection and storage. These tubes come in various sizes and colors, each indicating the type of additive present to facilitate different tests. However, it is essential to follow certain precautions when using vacutainer tubes to ensure accurate and reliable results.

Precautions When Using Vacutainer Tubes

1. Check Expiration Date

Before using any vacutainer tube, always check the expiration date to ensure that the additive within the tube is still viable. Using an expired tube may affect the integrity of the specimen and lead to inaccurate Test Results. Discard any tubes that have passed their expiration date and replace them with new ones.

2. Proper Labeling

Each vacutainer tube must be properly labeled with the patient's information, including name, date of birth, and identification number. Additionally, the tube should be labeled with the tests ordered to prevent any mix-ups or confusion in the laboratory. Proper labeling is crucial for accurate sample identification and result reporting.

3. Correct Order of Draw

When collecting multiple tubes of blood from a patient, it is essential to follow the correct order of draw to prevent Cross-Contamination and ensure accurate Test Results. The recommended order of draw is as follows:

1. Blood Culture tubes
2. Citrate tubes (Light Blue Top)
3. Serum tubes with or without Clot Activator (red or Gold Top)
4. Heparin tubes (green top)
5. EDTA tubes (Lavender Top)
6. Glycolytic inhibitor tubes (gray top)

4. Proper Mixing of the Sample

After collecting blood into the vacutainer tube, it is essential to gently invert the tube several times to ensure proper mixing of the sample with the additive. Inadequate mixing can lead to clot formation or improper preservation of the specimen, affecting the accuracy of the Test Results. Follow the recommended mixing instructions for each type of tube to maintain Sample Integrity.

5. Correct Handling and Storage

Proper handling and storage of vacutainer tubes are crucial to maintaining the integrity of the specimens. Store the tubes upright in a rack to prevent leakage or contamination. Avoid exposing the tubes to extreme temperatures or sunlight, as this may affect the stability of the additives. Transport the tubes to the laboratory promptly to ensure timely processing and analysis.

6. Dispose of Tubes Properly

After collecting the blood sample and transferring it to the appropriate department, dispose of the used vacutainer tubes properly. Follow the institutional guidelines for biohazard waste disposal to prevent any potential exposure to bloodborne pathogens. Do not reuse vacutainer tubes, as this may compromise the integrity of the specimen and lead to inaccurate Test Results.

Conclusion

When using vacutainer tubes for blood collection and storage, it is essential to take certain precautions to ensure accurate and reliable Test Results. By checking the expiration date, ensuring proper labeling, following the correct order of draw, mixing the sample correctly, handling and storing the tubes properly, and disposing of them appropriately, Healthcare Providers can maintain the integrity of the specimens and minimize the risk of errors in laboratory testing.
