n the fluid component of the blood containing all stable constituents except fibrinogen. When blood is allowed to clot and stand, a clear yellowish fluid, the serum, separates.

serum accelerator globulin,

serum marker,

n a specific indicator found in a blood test that identifies a disease.

serum protein determination, electrophoretic,

n separation of serum protein fractions (albumin, α-globulin, β-globulin, and γ-globulin) based on their different isoelectric points and mobility in an electric field. Electrophoretic patterns and concentrations are of value in evaluating the hyperglobulinemias. Electrophoretic evaluation of serum protein abnormalities is usually related to moving-boundary or paper-strip separation patterns.
