The SST is a type of tube used in which type of testing?

The SST, or Serum Separator Tube, is specifically designed for chemistry testing. This type of tube contains a gel that separates the serum from the cellular components of the blood after centrifugation. The separation allows for the collection of serum, which is the liquid portion of the blood that remains after coagulation. Since many chemistry tests require serum to analyze substances such as electrolytes, enzymes, and hormones, the use of an SST is standard practice in clinical laboratories for these types of tests. This makes the SST particularly valuable for performing a wide range of biochemical assays and supporting patient diagnosis and management.
