Which of the following is a common test performed with a SST tube?

The Comprehensive Metabolic Panel (CMP) is a common laboratory test that evaluates multiple metabolic functions in the body through a single blood sample. An SST tube, which stands for Serum Separator Tube, is specifically designed to facilitate serum collection after the blood has clotted and is centrifuged. This type of tube contains a gel that separates the serum from the cellular components, making it ideal for tests that require serum, such as the CMP.

The CMP includes tests that measure glucose levels, electrolyte and fluid balance, kidney function, and liver function, among others. Because it requires serum, the SST tube is perfect for collecting the sample, as it allows for clear separation of the serum after processing.
