Then it is separated into a liquid layer, the upper, which is called serum and a lower layer, which is solid clot. If the tube that was harvested blood of a substance anticoagulant (which prevents clotting) when blood no longer coagulates, but separates everything into two layers: the upper layer liquid consisting of plasma and lower layer, solid, constituted coagulated celuare the elements.
From these two components serum and blood plasma will perform biochemical and serological main medical tests. Of blood cellular components is achieved hematology. Hematology investigating the number, shape, and composition characteristics of cellular elements of the blood.
