Understanding the Benefits of Using SST Tubes in Clinical Diagnostic Labs

When you visit a clinical diagnostic lab for blood work, you may have noticed the phlebotomist using different types of tubes to collect samples. One common type of tube used in these settings is the SST Tube. But what exactly is an SST Tube, and why is it important in the field of clinical diagnostics? In this article, we will explore the significance of SST tubes and their role in obtaining accurate Test Results.

What is an SST Tube?

First and foremost, SST stands for "Serum Separator Tube." SST tubes are designed to simplify the blood collection process by allowing for the separation of serum from the blood cells. These tubes typically contain a gel separator that forms a barrier between the serum and the blood cells when the sample is centrifuged. This separation enables the clinical lab professionals to obtain a pure sample of serum for testing purposes.

How Does an SST Tube Work?

When a blood sample is collected into an SST Tube, the tube is usually inverted several times to ensure thorough mixing of the blood with the gel separator. The tube is then centrifuged at high speeds, causing the heavier blood cells to move to the bottom of the tube while the lighter serum remains on top of the gel separator. This separation process is essential for obtaining a clean serum sample without any contamination from blood cells.

Components of an SST Tube

1. Plastic or Glass Tube: SST tubes are typically made of plastic or glass material, depending on the manufacturer's specifications.
2. Gel Separator: The gel separator present in the tube helps in the efficient separation of serum from blood cells during centrifugation.
3. Additive: Some SST tubes may contain additives to preserve the stability of certain analytes present in the serum.

Uses of SST Tubes in Clinical Diagnostics

SST tubes are commonly used in clinical Diagnostic Labs for various types of blood tests, including but not limited to:

1. Basic Metabolic Panel: A group of tests that measure different chemicals in the blood, such as glucose, electrolytes, and kidney function markers.
2. Lipid Panel: A test that measures cholesterol and triglyceride levels in the blood to assess Cardiovascular Health.
3. Liver Function Tests: A series of tests that evaluate liver health by measuring enzymes, proteins, and other substances in the blood.
4. Rheumatoid Factor Test: A test that detects the presence of antibodies associated with autoimmune conditions like rheumatoid arthritis.
5. Thyroid Function Tests: A group of tests that assess thyroid hormone levels in the blood to diagnose thyroid disorders.

Advantages of Using SST Tubes

There are several advantages to using SST tubes for blood collection in clinical Diagnostic Labs:

1. Efficient Serum Separation: The gel separator in SST tubes allows for quick and efficient separation of serum from blood cells, reducing the processing time for samples.
2. Minimal Hemolysis: Hemolysis, the breakdown of red blood cells, can interfere with Test Results. SST tubes help minimize hemolysis by separating the serum from blood cells.
3. Convenience: SST tubes are easy to use and handle, making them a preferred choice for routine Blood Testing in clinical settings.
4. Compatibility: SST tubes are compatible with various types of automated analyzers used in clinical labs, ensuring reliable and accurate Test Results.

Challenges Associated with SST Tubes

While SST tubes offer many benefits, there are some challenges associated with their use in clinical diagnostics:

1. Incorrect Handling: Improper mixing of the blood sample with the gel separator or insufficient centrifugation can result in inaccurate Test Results.
2. Interference with Certain Tests: Some tests may be affected by the additives present in SST tubes, leading to potential inaccuracies in the results.
3. Storage Requirements: SST tubes need to be stored under specific conditions to maintain the stability of the gel separator and additives, which can be a logistical challenge in busy clinical labs.

Conclusion

Overall, SST tubes play a crucial role in the field of clinical diagnostics by facilitating the separation of serum from blood cells for accurate testing. These tubes offer various advantages, such as efficient serum separation, minimal hemolysis, and compatibility with automated analyzers. However, it is essential for lab professionals to handle SST tubes correctly to avoid potential issues with Test Results. By understanding the purpose and function of SST tubes, both patients and Healthcare Providers can ensure the reliability and accuracy of laboratory testing in clinical settings.
