What does the T-Gel component in an SST tube accomplish?

The T-Gel component in an SST (Serum Separator Tube) is specifically designed to separate serum from blood cells after centrifugation. During the centrifugation process, the T-Gel creates a barrier between the serum and the cellular components, preventing them from mixing. This separation is crucial for obtaining a clear serum sample, which is needed for various laboratory tests. The presence of this gel ensures that the serum is readily accessible for further analysis without interference from cellular material, allowing for more accurate test results. The efficiency of this separation is what makes SST tubes particularly useful in clinical settings.
