The SST in testing indicates what type of tube?

The SST in testing stands for Serum Separator Tube. This type of tube is commonly used in blood collection and is designed to separate serum from the cellular components of blood after centrifugation. The SST contains a gel that creates a barrier between the serum and the blood cells, allowing for easier collection and handling of serum samples for various laboratory tests.

Using a Serum Separator Tube is particularly beneficial because it minimizes the risk of contamination, as the gel prevents cellular material from mixing with the serum, ensuring accurate test results. Also, this tube is often used for chemistry tests which require a serum sample, making it an essential part of phlebotomy procedures.
