What tube typically used for a lipid panel is also known for use in routine biochemistry tests?

The SST, or Serum Separator Tube, is commonly used for lipid panels as well as various routine biochemistry tests due to its unique properties. It contains a gel that separates the serum from the blood cells after centrifugation, making it ideal for such analyses. The gel forms a barrier between the solid cellular components and the liquid serum, which allows for easier handling and minimizes the risk of contamination between the two layers. This is particularly important for lipid testing, as accurate measurements of lipids require clear serum.

In contrast, other tubes such as the yellow tube typically contain additives for specific tests like blood cultures, and the gray tube is mainly used for glucose tests or lactate measurements, which do not require serum. The red tube, while it can also be used for serum testing, lacks the separation gel that enhances the convenience and reliability of the SST for lipid panels and routine biochemistry tests. Thus, the SST is the appropriate choice for these applications.
