However even with trained observers visual assessment of the degree of hemolysis can be highly subjective and unreliable. Specimens with a light pink hue indicate slight hemolysis whereas deep red specimens represent gross hemolysis. For most routine analytes serum and plasma measurement results are equivalent but due to platelet clotting platelet substances eg potassium lactate dehydrogenase calcium magnesium etc can be higher in serum than plasma.

Plasma is the blood fluid that contains blood clotting agents. In the tests we talked about we add reagents to plasma which has all the coagulation factors in it already to kick off the coagulation cascade and see how long it takes to make. The serum is the primary source of.
