What does SST stand for in phlebotomy?

SST stands for serum separator tube in phlebotomy. This type of tube is specifically designed to facilitate the separation of serum from the blood cells after the sample has been centrifuged. The SST contains a gel that forms a barrier between the serum and the blood cells, allowing for easier and cleaner isolation of the serum, which is critical for many laboratory tests. This separation is essential for obtaining accurate test results, especially for chemistry tests that require serum.

The other options do not accurately describe the SST. A serum sample tube is a generic term that doesn't specify the separator feature, and standard specimen tube and simple serum tube do not reflect the unique design and function of the SST in the context of blood collection and processing. Understanding the specific terminology used in phlebotomy is crucial for effective communication and proper laboratory practices.
