Blood should be collected from patient slowly and smoothly without applying high force to avoid haemolysis. Blood which added into tubes containing additive should be inverted carefully to fully homogenize the solution.
The blood in the serum separator tubes should be allowed to clot for at least 30 minutes in a vertical position prior to centrifugation. Short clotting times will result in fibrin formation, which may affect the complete gel barrier formation.
