Introduction

Phlebotomy is a crucial procedure in healthcare settings, involving the collection of blood samples for diagnostic testing. Proper technique in drawing blood collection tubes is essential to ensure accurate Test Results and patient safety. In the United States, there is a specific order in which different colored blood collection tubes should be drawn during a phlebotomy procedure to prevent Cross-Contamination and ensure Sample Integrity.

Why is the Order of Drawing Blood Collection Tubes Important?

The order in which blood collection tubes are drawn during a phlebotomy procedure is critical for several reasons:

Preventing Cross-Contamination

Each blood collection tube contains different additives that are necessary for specific tests. Drawing tubes in the wrong order can lead to sample contamination and inaccurate Test Results. By following a specific order, phlebotomists can prevent Cross-Contamination between tubes and ensure the integrity of each sample.

Ensuring Accuracy of Test Results

The additives present in blood collection tubes are designed to preserve the integrity of the blood sample and prevent clotting or other changes that could alter Test Results. Drawing tubes in the correct order ensures that the additives do not mix and affect the quality of the sample, leading to more accurate Test Results.

Improving Patient Care

By following the recommended order of drawing blood collection tubes, Healthcare Providers can improve patient care by reducing the risk of errors in testing and ensuring that patients receive accurate diagnoses and appropriate treatment based on reliable Test Results.

Recommended Order of Drawing Blood Collection Tubes

In the United States, the Clinical and Laboratory Standards Institute (CLSI) recommends the following order of drawing blood collection tubes based on the color of the tubes:

  1. Yellow or SPS (Sterile, Peroxide, Sterile) tubes for blood cultures
  2. Light blue tubes for coagulation tests
  3. Red or gold tubes for chemistry tests
  4. Green tubes for basic metabolic panels and STAT chemistry tests
  5. Lavender tubes for complete blood counts (CBC) and blood bank tests
  6. Gray tubes for glucose tests
  7. Dark blue tubes for trace element and Toxicology tests

Conclusion

Following the specific order of drawing blood collection tubes during a phlebotomy procedure is essential for ensuring accurate Test Results, preventing Cross-Contamination, and improving patient care in home healthcare, clinical lab, and hospitals. By adhering to the recommended guidelines for drawing blood collection tubes, Healthcare Providers can enhance the quality of diagnostic testing and contribute to better outcomes for patients.
