How long can blood sit in tubes?

Whole blood can be stored at 4–8°C for up to 24 hours before the serum is separated, but it must not be frozen. Whole blood should be allowed to clot and then centrifuged at 1000 × gravitational units (g) for 10 minutes to separate the serum.

What does the SST tube test for?

Serum Separator Tube (SST®) for serum determinations in chemistry and serology. Contains separator gel and should not be used for toxicology or drug testing. Inversions ensure mixing of clot activator with blood. Blood clotting time 30 minutes.

Although the veins located in the antecubital area should be considered first for vein selection, there are alternate sites available for venipuncture.
