Serum Separator Tubes: Essential Tools for Accurate Test Results in Phlebotomy Procedures

Summary

• Serum separator tubes are essential tools in phlebotomy procedures in the United States.
• Proper handling and processing of serum separator tubes are crucial to ensure accurate Test Results.
• Understanding the specific testing requirements for serum separator tubes is vital for Healthcare Providers in clinical labs and hospitals.

Introduction

In the United States, phlebotomy procedures play a vital role in the healthcare industry by collecting blood samples for diagnostic testing. Serum separator tubes are commonly used in phlebotomy to separate serum from whole blood for various laboratory tests. Understanding the specific testing requirements for serum separator tubes is essential for Healthcare Providers in clinical labs and hospitals to ensure accurate Test Results and patient care.

What are Serum Separator Tubes?

Serum separator tubes, also known as SST tubes, are blood collection tubes with a gel separator that separates serum from whole blood after centrifugation. The gel forms a barrier between the serum and the blood cells, allowing for easy separation and retrieval of the serum for testing.

Components of Serum Separator Tubes

Serum separator tubes typically consist of the following components:

1. Tube with a stopper
2. Gel separator
3. Additive for clot activation (optional)

Function of Gel Separator

The gel separator in serum separator tubes acts as a physical barrier between the serum and the blood cells, preventing mixing and allowing for easy separation of the serum during the centrifugation process.

Specific Testing Requirements for Serum Separator Tubes

When using serum separator tubes for phlebotomy procedures, Healthcare Providers in clinical labs and hospitals must adhere to specific testing requirements to ensure accurate and reliable Test Results. Some of the key testing requirements include:

Proper Storage and Handling

It is essential to store serum separator tubes in a controlled environment to maintain the integrity of the gel separator and prevent contamination. Healthcare Providers should follow these guidelines for proper storage and handling:

1. Store tubes at room temperature away from direct sunlight and heat sources.
2. Avoid freezing or exposing tubes to extreme temperatures.
3. Check the expiration date and discard expired tubes.

Correct Order of Draw

When performing phlebotomy procedures with multiple tubes, Healthcare Providers must follow the correct order of draw to prevent Cross-Contamination and ensure accurate Test Results. The recommended order of draw for serum separator tubes is:

1. Yellow or sterile tubes for blood cultures
2. Light blue tubes for coagulation studies
3. Red or tiger-top tubes for serum tests

Centrifugation Process

Proper centrifugation of serum separator tubes is crucial to ensure complete separation of serum from blood cells. Healthcare Providers should follow these steps for the centrifugation process:

1. Place tubes in a balanced manner in the centrifuge to prevent breakage.
2. Centrifuge tubes at the recommended speed and time to ensure optimal separation.
3. Allow tubes to sit undisturbed after centrifugation to prevent remixing of serum and blood cells.

Common Tests Using Serum Separator Tubes

Serum separator tubes are used for a wide range of laboratory tests that require serum samples for analysis. Some of the common tests performed using serum separator tubes include:

1. Complete Blood Count (CBC)
2. Basic Metabolic Panel (BMP)
3. Liver Function Tests (LFTs)
4. Lipid Profile
5. Thyroid Function Tests

Conclusion

Understanding the specific testing requirements for serum separator tubes is essential for Healthcare Providers in clinical labs and hospitals to ensure accurate and reliable Test Results. Proper storage, handling, correct order of draw, and centrifugation process are critical aspects of using serum separator tubes in phlebotomy procedures. By following these guidelines, Healthcare Providers can optimize the quality of patient care and diagnostic testing in the United States.
