How Serum Separation Tubes Revolutionized Blood Collection Techniques

Serum separation tubes have revolutionized the way blood is collected for medical testing. These specialized tubes are designed to separate blood into its various components, making it easier and more efficient to analyze for diagnostic purposes. In this article, we will explore the benefits of serum separation tubes and how they have improved blood collection techniques.

What are Serum Separation Tubes?

Serum separation tubes, also known as SSTs, are vacuum-sealed glass or plastic tubes that contain a gel or other substance that separates blood into its components. The tube is filled with blood and then inverted several times to mix the blood with the separating substance. The tube is then centrifuged to separate the serum from other components of the blood.

Benefits of Serum Separation Tubes

One of the primary benefits of serum separation tubes is that they simplify and streamline the process of collecting and analyzing blood samples. Prior to their invention, medical professionals had to use multiple containers and perform additional steps to separate serum from other components in the blood sample.

Another benefit is that serum separation tubes reduce the risk of contamination during collection and analysis. The vacuum-sealed tube prevents air from entering, which can cause oxidation or bacterial growth in the sample. This ensures that test results are accurate and reliable.

Serum separation tubes also ensure consistent results across multiple samples. Because they separate serum from other components in a standardized manner, test results can be compared across different samples without variation due to inconsistent processing methods.

Applications of Serum Separation Tubes

Serum separation tubes are used in a wide range of medical applications, including routine laboratory testing, disease diagnosis, and drug monitoring. They allow lab technicians to quickly analyze patient samples without having to perform additional steps such as pipetting or centrifuging.

Additionally, because SSTs allow for rapid processing of large numbers of samples at once, they are useful in clinical trials and research studies where many samples need to be collected and analyzed in a short period of time.

Serum Separation Tubes vs. Traditional Blood Collection Methods

Serum separation tubes have several advantages over traditional blood collection methods, such as using a syringe and needle to draw blood into a container. These traditional methods can be time-consuming and require additional steps for separating serum from other components. Additionally, these methods carry a higher risk of contamination or infection due to the handling of multiple containers.

In contrast, serum separation tubes simplify the process by combining blood collection and serum separation into one step. They also reduce the risk of contamination or infection by minimizing the number of containers used.


Serum separation tubes have revolutionized blood collection techniques by streamlining the process, reducing the risk of contamination, ensuring consistent results, and simplifying analysis for medical professionals. Their applications range from routine laboratory testing to clinical trials and research studies. In comparison to traditional blood collection methods, SSTs offer numerous advantages that make them an essential tool in modern medical practice.
