The Evolution Of The Order Of Draw In Blood Collection

Summary

• The order of draw for blood collection has evolved in recent years due to advancements in technology and research.
• Changes in the order of draw aim to minimize the risk of sample contamination and ensure accurate Test Results.
• Healthcare Providers must stay informed about the current order of draw guidelines to provide quality patient care.

Introduction

Proper blood sample collection is crucial for accurate diagnostic testing and patient care. Over the years, the order of draw for blood collection has undergone significant changes to improve the quality of samples and reduce the risk of contamination. In this article, we will explore how the order of draw has evolved in recent years and why it is essential for Healthcare Providers to adhere to these guidelines.

The Importance of the Order of Draw

The order of draw refers to the sequence in which different types of blood collection tubes are filled during Venipuncture. Following the correct order of draw is essential to prevent contamination of blood samples and ensure accurate Test Results. By collecting blood in a specific order, Healthcare Providers can minimize the risk of additives from one tube affecting the results of subsequent tubes.

Old Order of Draw

Historically, the order of draw was established based on the type of additives present in blood collection tubes. The old order of draw typically followed this sequence:

1. Plain (non-additive) tubes
2. Citrate tubes
3. Serum tubes
4. Heparin tubes
5. EDTA tubes
6. Other additive tubes

New Order of Draw

Advancements in technology and research have led to changes in the order of draw in recent years. The new order of draw prioritizes the collection of certain tubes before others to improve sample quality and reduce the risk of contamination:

1. Collection tubes with clot activators
2. Blood Culture tubes
3. Serum tubes
4. Heparin tubes
5. EDTA tubes
6. Glycolytic inhibitor tubes

Reasons for the Change

The updated order of draw is based on scientific evidence and best practices in phlebotomy. There are several reasons why the order of draw has changed in recent years:

1. Minimizing the risk of sample contamination: Placing tubes with clot activators first helps prevent clotting in subsequent tubes, reducing the risk of sample contamination and ensuring accurate Test Results.
2. Improving sample quality: By prioritizing the collection of Blood Culture tubes early in the process, Healthcare Providers can increase the likelihood of detecting bloodstream infections and other serious conditions.
3. Standardizing procedures: Following a consistent order of draw helps Healthcare Providers maintain Quality Control and adhere to best practices in blood collection.

Implications for Healthcare Providers

As the order of draw continues to evolve, it is essential for Healthcare Providers to stay informed about the latest guidelines and recommendations. Adhering to the correct order of draw can have significant implications for patient care and diagnostic testing:

1. Accurate Test Results: Following the proper order of draw can help ensure that blood samples are collected in a way that minimizes the risk of contamination and produces accurate Test Results.
2. Patient safety: By collecting blood samples in the correct order, Healthcare Providers can reduce the likelihood of errors and improve patient safety during diagnostic testing.
3. Quality assurance: Adhering to the current order of draw guidelines is essential for maintaining quality assurance in laboratory testing and ensuring that patients receive the best possible care.

Conclusion

The order of draw for blood collection has changed in recent years to reflect advancements in technology and research. Healthcare Providers must stay informed about the current guidelines to ensure that blood samples are collected in a way that minimizes the risk of contamination and produces accurate Test Results. By following the correct order of draw, Healthcare Providers can provide quality patient care and contribute to improved diagnostic testing outcomes.
