Key Considerations for Selecting Plastic Tubes for Blood Collection: Material, Additives, and Closure Types

Summary

• Choosing the right plastic tubes for blood collection is crucial for accurate Test Results and patient safety.
• Consider factors such as tube material, additives, and closure type when selecting plastic tubes for blood collection.
• Consult with healthcare professionals and follow industry guidelines to ensure that the plastic tubes meet the necessary standards.

Introduction

When it comes to blood collection, selecting the appropriate plastic tubes is essential for ensuring accurate Test Results and maintaining patient safety. With different tube materials, additives, and closure types available on the market, healthcare professionals must carefully consider their options before making a decision. In this article, we will discuss the key considerations that should be made when selecting plastic tubes for blood collection.

Tube Material

The material of the plastic tubes plays a significant role in blood collection. Different materials may interact with the blood sample in various ways, potentially affecting the Test Results. Some common tube materials used for blood collection include:

1. Polypropylene: Polypropylene tubes are widely used in blood collection due to their compatibility with most additives and anticoagulants. They are durable and resistant to breakage, making them ideal for storage and transportation.
2. Polystyrene: Polystyrene tubes are transparent, allowing for easy visual inspection of the blood sample. However, they are less durable than polypropylene tubes and may be more prone to breakage.
3. PET (Polyethylene Terephthalate): PET tubes are lightweight and shatterproof, making them suitable for high-speed centrifugation. They are also transparent, allowing for visual inspection of the blood sample.

Additives

Many plastic tubes for blood collection come with additives or coatings to help preserve the integrity of the blood sample and improve the accuracy of Test Results. Some common additives used in blood collection tubes include:

1. Anticoagulants: Anticoagulants prevent blood from clotting and are essential for collecting samples for coagulation tests. Common anticoagulants used in plastic tubes include EDTA, Heparin, and citrate.
2. Separator Gels: Separator gels are used to separate serum from the blood cells during centrifugation. They help in obtaining clear serum samples for various biochemical tests.
3. Clot Activators: Clot activators promote the clotting of blood and are used in tubes for collecting samples for serum tests. They help to accelerate the clotting process, making the serum available for testing sooner.

Closure Type

The closure type of the plastic tubes is another important consideration when selecting tubes for blood collection. The closure ensures that the blood sample remains secure and prevents contamination. Some common closure types for plastic blood collection tubes include:

1. Conventional Stoppers: Conventional stoppers are rubber or plastic closures that provide a secure seal for the tube. They are easy to use and are suitable for most blood collection applications.
2. Screw Caps: Screw caps provide a more secure closure for the tubes, reducing the risk of leakage or contamination. They are ideal for samples that require long-term storage or transportation.
3. Push Caps: Push caps are convenient closures that can be easily pushed on and off the tube. They provide a secure seal and are suitable for quick and easy access to the blood sample.

Consultation and Compliance

When selecting plastic tubes for blood collection, healthcare professionals should consult with laboratory technicians, phlebotomists, and other experts in the field. These professionals can provide valuable insights and recommendations based on their experience and knowledge of industry best practices. Additionally, it is essential to ensure that the plastic tubes comply with industry standards and guidelines for blood collection. Healthcare facilities should follow the recommendations of organizations such as the Clinical and Laboratory Standards Institute (CLSI) to ensure that the tubes meet the necessary requirements for accurate and reliable Test Results.

Conclusion

Choosing the right plastic tubes for blood collection is a critical step in ensuring the accuracy of Test Results and maintaining patient safety. Healthcare professionals should consider factors such as tube material, additives, and closure type when selecting plastic tubes for blood collection. By consulting with experts in the field and following industry guidelines, healthcare facilities can ensure that the plastic tubes meet the necessary standards for blood collection.
