serum

pl. sera, serums [L.] the clear portion of any animal or plant fluid that remains after the solid elements have been separated out. The term usually refers to blood serum, the clear, straw-colored, liquid portion of the plasma that does not contain fibrinogen or blood cells, and remains fluid after clotting of blood.
Blood serum from animals whose bodies have built up antibodies is called antiserum or immune serum. Inoculation with such an antiserum provides temporary, or passive, immunity against the disease.

serum albumin mastitis test
a high concentration of serum albumin in milk indicates the presence of mastitis in the quarter.
antilymphocyte serum
serum breaks
in classical swine fever (hog cholera) vaccination when a serum-simultaneous vaccination program is not effective and it is assumed that the hyperimmune serum was ineffective.
serum clot time
see prothrombin consumption test.
serum enzymes
enzymes of individual tissues are released into the blood when the tissue is damaged or when there is much activity in it. The levels are used as a measure of activity or injury.
serum-fast
resistant to the effects of serum.
serum glutamic-oxaloacetic transaminase (SGOT)
serum glutamic-pyruvic transaminase (SGPT)
immune serum
serum from an immunized animal, containing specific antibody or antibodies.
serum osmolality
a measure of the number of dissolved particles per unit of water in serum. See also serum osmolality.
pooled serum
the mixed serum from a number of animals.
serum protein
see serum protein.
serum sickness
a group of immediate or antibody-mediated hypersensitivity reactions (also referred to as type III hypersensitivities) that includes Arthus reaction, serum sickness and immune complex diseases. The pathogenesis involves formation of bulky antibody-antigen complexes in the walls of small blood vessels; the complexes fix complement and cause necrosis and thrombus formation. There is infiltration of polymorphonuclear cells from which lysosomal enzymes are released.
serum-simultaneous immunization
an outdated method of vaccination, most popular at one time in the vaccination of pigs against classical swine fever (hog cholera). Live virus and antiserum to the virus were injected into the patient simultaneously; breakdowns in the system were frequent, leading to severe outbreaks of the target disease.
serum thymic factor
a humoral factor enhancing T lymphocyte responsiveness.
