If a blood sample is collected into an evacuated tube without an additive, the blood will clot naturally because there is no anticoagulant present to prevent clotting. This can lead to inaccurate test results as the clot formation may interfere with various analyses requiring liquid blood.
To obtain serum, the coagulated blood is left to clot at room temperature for approximately 15 to 30 minutes. After it is completely clotted, it is rimmed using an applicator stick and then centrifuged for approximately 5-10minutes at 2500 revolutions per minute. Then the supernatant fluid is separated.

The fact that 0 is the additive identity.
The additive in red-gray or red-black speckled collection tubes is typically a clot activator and gel separator. These additives help to separate the blood sample from the serum after centrifugation, allowing for easier testing of the serum without interference from clots or cells.
An SST (serum separator tube) contains a gel barrier that separates blood cells from serum when the tube is centrifuged. The gel allows for easier extraction of serum for laboratory testing without contaminating it with blood cells.

The fact that 8 + 0 = 8 demonstrates the additive identity property of 0. The number 0 can be added to any quantity without altering the value of that quantity. This is because 0 is the additive IDENTITY.
