Key Differences Between SST Tube and Red Top Tube in Blood Collection - United States

Summary

• SST Tube and Red Top tube are both commonly used for blood collection in medical laboratories in the United States.
• SST tubes contain a gel separator that helps to separate serum from cells, while Red Top tubes do not contain any additives.
• The choice between using an SST Tube and a Red Top tube depends on the specific tests being performed and the laboratory's standard operating procedures.

Introduction

When it comes to blood collection in a medical laboratory setting, there are several different types of tubes that can be used. Two of the most common types are the SST Tube and the Red Top tube. These tubes each have their own unique characteristics and are used for specific purposes in the laboratory. In this article, we will explore the key differences between using an SST Tube and a Red Top tube for blood collection in the United States.

SST Tube

The SST Tube, which stands for serum separator tube, is a type of blood collection tube that contains a gel separator at the bottom. The gel separator helps to separate the serum from the blood cells after the tube has been centrifuged. This allows for easier and more accurate testing of the serum component of the blood sample.

Some key features of SST tubes include:

1. Gel separator at the bottom of the tube
2. Allows for easy separation of serum from cells
3. Commonly used for chemistry tests

Benefits of Using SST Tubes

1. Convenient and time-saving
2. Reduces the risk of contamination
3. Provides a clear and clean serum sample

Drawbacks of Using SST Tubes

1. May be more expensive than other types of tubes
2. Not suitable for all types of tests
3. Requires careful handling to prevent gel disruption

Red Top Tube

Unlike SST tubes, Red Top tubes do not contain a gel separator or any other additives. These tubes are simply used to collect and store blood samples for testing. The lack of additives in Red Top tubes makes them ideal for certain types of tests that require whole blood or serum without any additional substances.

Some key features of Red Top tubes include:

1. No additives or gel separator
2. Ideal for tests that require whole blood or serum only
3. Commonly used for blood banking and serological tests

Benefits of Using Red Top Tubes

1. Cost-effective option for blood collection
2. Suitable for a wide range of tests
3. Simple and easy to use

Drawbacks of Using Red Top Tubes

1. Cannot separate serum from cells
2. May require additional processing steps for certain tests
3. Not suitable for tests that require a clear serum sample

Choosing Between SST Tube and Red Top Tube

When deciding whether to use an SST Tube or a Red Top tube for blood collection in a medical laboratory setting, it is important to consider the specific requirements of the tests being performed. Some tests may require a clear serum sample, which would make an SST Tube the preferred choice. Other tests may require whole blood or serum without any additives, in which case a Red Top tube would be more appropriate.

It is also important to consider the laboratory's standard operating procedures and any guidelines set forth by regulatory bodies such as the Clinical Laboratory Improvement Amendments (CLIA). These guidelines may dictate which type of tube should be used for certain tests to ensure accurate and reliable results.

Conclusion

In conclusion, both SST tubes and Red Top tubes have their own unique advantages and disadvantages when it comes to blood collection in a medical laboratory setting in the United States. The choice between using an SST Tube and a Red Top tube ultimately depends on the specific tests being performed and the laboratory's standard operating procedures. By understanding the key differences between these two types of tubes, laboratory professionals can make informed decisions that will ensure the accuracy and reliability of the Test Results.
