Allow blood to clot at ambient temperature for 20 to 30 minutes. The theory behind increased potassium after recentrifugation is that on initial centrifugation, the cells are separated from the serum by thixotropic gel. Centrifugation at 600 x g brings down the red cells quickly.

Hemolysis is the most common reason for sample rejection by laboratories.Hemolysis is defined as the rupture of red blood cells with the release of hemoglobin and the intracellular components into the plasma. Brown-coloured serum is normally caused by serious conditions such as massive intravascular haemolysis or methemoglobinaemia. Then centrifuse 3000rpm for 10 minutes. Hemolysis. This is to prevent excessive vibration and potential breakage of the specimen tube, and is also necessary to properly separate the serum A 10 ml tube of whole blood will be collected following standard procedures Serum is the watery, pale yellow part of blood. The resulting supernatant is designated serum. The Plasma is the watery or liquid fluid portion of the blood, in which several blood cells are diluted and is obtained after the centrifugation by adding the anti-coagulating agents.The fluid or undiluted part of the blood, obtained after the complete coagulation of the blood, without adding an anticoagulating agent is called serum.
