Understanding the Differences in Blood Clotting Additives Between SST Tube and Red Top Tube

Summary

• SST tubes contain a gel separator which helps in separating serum from blood cells, while Red Top tubes do not contain any additives for blood clotting.
• The gel separator in SST tubes can interfere with certain laboratory tests, so it is important to carefully select the appropriate tube for different testing purposes.
• Understanding the differences in blood clotting additives between SST and Red Top tubes is crucial for phlebotomists to ensure accurate and reliable Test Results.

SST Tube vs. Red Top Tube: Understanding the Differences in Blood Clotting Additives

Phlebotomy procedures play a crucial role in the healthcare system by collecting blood samples for laboratory testing. Different types of blood collection tubes are used depending on the tests that need to be performed. Two commonly used tubes are the Serum Separator Tube (SST) and the Red Top tube. Understanding the differences in blood clotting additives between these two tubes is essential for phlebotomists to ensure accurate Test Results.

What is an SST Tube?

An SST Tube, also known as a serum separator tube, contains a gel separator that helps in separating serum from blood cells after centrifugation. The gel forms a barrier between the serum and the blood cells, allowing for easy and clean separation of the two components. SST tubes are commonly used for tests that require serum samples, such as blood chemistry tests.

What is a Red Top Tube?

A Red Top tube, on the other hand, does not contain any additives for blood clotting or separation. Blood collected in a Red Top tube will naturally clot over time, and the serum will separate from the blood cells. Red Top tubes are used for tests that require a non-anticoagulated blood sample, such as blood typing and antibody screening.

Differences in Blood Clotting Additives

The key difference between an SST Tube and a Red Top tube lies in the presence of a gel separator in the SST Tube. The gel separator in the SST Tube helps in clotting the blood faster by activating clotting factors and promoting the formation of a stable clot. This allows for quicker separation of serum from blood cells, making it ideal for tests that require serum samples.

1. SST Tube:
   1. Contains a gel separator that promotes faster blood clotting.
   2. Separates serum from blood cells after centrifugation.
   3. Ideal for tests that require serum samples.
2. Red Top Tube:
   1. Does not contain any additives for blood clotting.
   2. Blood naturally clots over time, and serum separates from blood cells.
   3. Ideal for tests that require a non-anticoagulated blood sample.

Considerations for Phlebotomists

When collecting blood samples for laboratory testing, phlebotomists must carefully consider the type of tube to use based on the specific tests that need to be performed. Using the wrong tube can lead to inaccurate Test Results and potentially impact patient care. Here are some key considerations for phlebotomists when selecting between SST tubes and Red Top tubes:

1. Test Requirements:
   1. Understand the testing requirements and whether a serum sample or non-anticoagulated blood sample is needed.
2. Tube Selection:
   1. Choose the appropriate tube based on the test requirements to ensure accurate and reliable results.
3. Labeling:
   1. Properly label the tubes to prevent mix-ups and ensure traceability throughout the testing process.

Conclusion

In conclusion, the differences in blood clotting additives between an SST Tube and a Red Top tube are crucial for phlebotomists to understand. While SST tubes contain a gel separator that promotes faster blood clotting and separation of serum from blood cells, Red Top tubes do not contain any additives for blood clotting. Careful consideration of the tube selection based on the specific testing requirements is essential to ensure accurate and reliable Test Results. By understanding these differences, phlebotomists can optimize the blood collection process and contribute to the overall effectiveness of healthcare delivery in the United States.
