Dark Blue Vacutainers: Importance and Usage in Phlebotomy Procedures

Summary

  • Dark blue vacutainers are used in phlebotomy procedures in the United States.
  • The additive or substance present in a dark blue vacutainer is Sodium Citrate.
  • This additive helps to prevent blood clotting and is commonly used for coagulation studies.

Introduction

Phlebotomy is a vital part of healthcare where blood is drawn from patients for various tests and procedures. Different colored vacutainers are used for collecting different types of blood samples. In the United States, one commonly used type of vacutainer is the dark blue one.

What is a Dark Blue Vacutainer?

A dark blue vacutainer is a type of blood collection tube that is used in phlebotomy procedures. It is usually made of glass or plastic and has a stopper on one end. The dark blue color of the tube indicates that it contains a specific additive or substance that is important for certain types of blood tests.

What is the Additive in a Dark Blue Vacutainer?

The additive or substance present in a dark blue vacutainer is Sodium Citrate. Sodium Citrate is an anticoagulant, which means it prevents blood from clotting. This is essential for certain types of blood tests, particularly coagulation studies.

Why is Sodium Citrate Used?

Sodium Citrate is used in dark blue vacutainers because it helps to maintain the integrity of the blood sample by preventing it from clotting. This is important for tests that require the blood to remain in a liquid state, such as coagulation studies that measure the time it takes for blood to clot.

Common Tests Using Dark Blue Vacutainers

Dark blue vacutainers with Sodium Citrate are commonly used for coagulation studies, including:

  1. Prothrombin Time (PT) test
  2. Partial Thromboplastin Time (PTT) test
  3. Activated Partial Thromboplastin Time (aPTT) test
  4. Thrombin Time test

Conclusion

Dark blue vacutainers with Sodium Citrate play a crucial role in phlebotomy procedures in the United States. By preventing blood clotting, Sodium Citrate ensures that blood samples remain suitable for coagulation studies and other tests that require liquid blood samples. Understanding the role of additives in vacutainers is essential for healthcare professionals to ensure accurate and reliable Test Results.
