I usually get the blood by decapitation, ideally on isofluran anaesthesia. It also contains clot activator. Hemolyzed or grossly lipemic samples. After centrifugation of blood into its components by a SST (serum separator tube), the serum may appear something other than clear. This helps prevent re-mixing of the layers if the transfer of the serum/plasma is delayed or the tube is accidentally knocked over after Clot activators Chemistry tests requiring no additives Mix 8-10 times and allow blood to clot for 30-60 minutes at room temperature before centrifugation. Ten minutes is more than enough time to separate red cell pellet from dilute plasma supernatant. Grossly lipemic specimens should be cleared by ultracentrifugation. Should clot for 60 minutes, while serum separator tubes centrifuge for 10 min within 45-60 minutes after to! 1. Separation gel is commonly used in some blood collection tubes where it forms a semi-permanent barrier between blood cells and the serum/plasma layer after centrifugation.
