Indicate contents of tube on label (serum, plasma, etc). Improper centrifugation Test results can also be altered if specimens are not centrifuged properly. An alternative is to use tubes containing lithium heparinate which prevents coagulation and allows centrifugation immediately after the arrival of the tubes in the laboratory. Sufficient amount of serum and cells and serum completely separated be transferred from an SST tube the. It is helpful to be able to recognize these differences because sometimes they can interfere with Chemistry tests.

After centrifugation, the inert acrylic gel at the bottom of the tube normally occupies the middle position between the cells (clot) and the serum, as its density is intermediate between theirs. Before Allow the specimen(s) to sit at ambient temperature until a clot has formed. Manufacturers of blood collection tubes typically recommend centrifugation for 10 to 15 min depending on the type of tube, 1,2 and WHO also, in general, proposes a centrifugation time of at least 10 min and 1500 g for serum and at least 15 min and 2000-3000 g for plasma. The cells and clotting factors must be removed from the blood sample by allowing adequate time for a clot to form. After centrifugation, remove the plasma and place it into a polypropylene microcentrifuge tube or a 12 X 75 polypropylene tube. Serum gel tubes should be centrifuged within 2 hours of collection. Mix well. The resulting supernatant is designated serum. If it turned red colour, we could be explain the hemolysis will occur when animal test. ii.
