What does SST stand for in common laboratory terminology?

• A. Serum Separator Tube
• B. Serum Spectator Tube
• C. Serum Specimen Tube
• D. Serum Stabilizer Tube

Answer: (A)

In lab terminology, SST stands for Serum Separator Tube. This tube is designed to yield serum for testing by using a gel that forms a barrier between the serum and the blood cells after centrifugation. It also usually contains a clot activator to help the blood clot faster, so serum can be obtained promptly. The gel barrier keeps the serum clean from cellular components, which is important for accurate chemistry and serology tests. The tube is typically color-coded with a gold-cap lid, signaling its separator function. Other names like Spectator, Specimen, or Stabilizer Tube aren’t used for this tube in standard practice.
