Which color tube is commonly associated with serum separator tubes (SST), such as Gold or Tiger Top?

Explanation:
SST tubes are identified by their gold color, often called Tiger Top. This color signals that the tube contains a clot activator and a serum-separating gel, which after centrifugation leaves a clean layer of serum for chemistry tests. The gold top distinguishes these tubes from others: red tops are plain clot activator tubes without a gel, blue tops contain citrate for coagulation testing, and tan isn’t a standard color for SST in typical practice. So the gold color is the telltale cue that the tube is an SST used for serum separation.
