What is the mode of action for the Gold Tube Top?

The mode of action for the gold tube top, often referred to in blood collection, is that it is designed to separate serum from the blood after the specimen has been centrifuged. When blood is collected in a gold-top tube, which usually contains a gel separator and a clot activator, the tube allows for the serum to be clearly separated from the cellular components of the blood following centrifugation. This is vital for performing various laboratory tests as it ensures that the serum can be easily accessed and analyzed without interference from cells.

In addition, this separation is crucial for accurate test results, enabling better diagnostic and clinical decisions. The gel separator acts as a barrier, maintaining the integrity of the serum in a distinct layer above the cellular components, providing a clean sample for testing. This contrasts with other tube types that may serve different purposes, such as those that promote coagulation or preserve specific elements in the blood.
