It has approximately the same volume (55%) as plasma and differs from it only by the absence of fibrinogen. See Fibrinogen Blood serum contains 6–8% solids, including macromolecules such as albumin, antibodies and other globulins, and enzymes; peptide and lipid-based hormones; and cytokines; as well as certain nutritive organic materials in small amounts, such as amino acids, glucose, and fats. Somewhat less than 1% of the serum consists of inorganic substances. Small amounts of respiratory gases are dissolved in the serum, as is the gas nitric oxide, which serves as a chemical messenger and vasodilator. Small amounts of waste material are also present. These substances, along with other small molecules which are not bound to blood proteins, are filtered out as blood flows through the kidney. See Blood, Kidney Certain types of sera, both human and animals, are used in clinical medicine. Immune serum and hyperimmune serum either are developed by naturally occurring disease or are deliberately prepared by repeated injection of antigens to increase antibody titer for either diagnostic tests or the treatment of active disease. These sera are referred to as antisera, since they have a specific antagonistic action against specific antigens. See Antibody, Antigen, Biologicals, Immunity By custom, the clear portion of any liquid material of animal origin separated from its solid or cellular elements is also referred to as sera. These fluids are more properly referred to as effusions. See Serology serum[′sir·əm] (physiology) The liquid portion that remains when blood clots spontaneously and the formed and clotting elements are removed by centrifugation; it differs from plasma by the absence of fibrinogen. serum1.

serum [se´rum] (pl. serums, se´ra) (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 persons or 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, and is used when a person has already been exposed to or has contracted the disease. Diseases in which passive immunization is sometimes used include diphtheria, tetanus, botulism, and gas gangrene.antilymphocyte serum (ALS) antiserum derived from animals that have been immunized against human lymphocytes, a powerful nonspecific immunosuppressive agent that causes destruction of circulating lymphocytes.antirabies serum antiserum obtained from the blood serum or plasma of animals immunized with vaccine" >rabies vaccine; used for postexposure prophylaxis against rabies if globulin" >rabies immune globulin is unavailable.blood grouping s's preparations containing particular antibodies against red cell antigens, used for blood typing. Those most commonly used are the anti-A and anti-B blood grouping serums used to determine ABO blood types and the anti-Rh blood grouping serums (anti-D, anti-C, anti-E, anti-c, and anti-e) used to determine Rh blood types.serum glutamic-oxaloacetic transaminase (SGOT) see aspartate transaminase.serum glutamic-pyruvic transaminase (SGPT) see alanine transaminase.immune serum antiserum.pooled serum the mixed serum from a number of individuals.serum sickness a hypersensitivity reaction following the administration of foreign serum or other antigens; it is marked by urticarial rashes, edema, adenitis, joint pains, high fever, and prostration. Reactions to antitoxin" >tetanus antitoxin derived from horse serum were especially common but are now rare owing to refinement of the antigenic components.serum sickness syndrome a serum sickness–like hypersensitivity reaction occurring after the administration of certain drugs. It is marked clinically by low-grade fever, urticaria, facial edema, pain and swelling of the joints, and lymphadenopathy, and occasionally may be associated with neuritis of the brachial plexus, guillain-barré syndrome, periarteritis nodosa, and nephritis.se·rum, pl. se·rums, se·ra (sē'rum, -ŭmz, -ă), Avoid the colloquial or jargonistic use of this word in the sense of 'any biologic agent' ("allergy serum") or 'any injected drug' ("truth serum").1.

- (also called
SerumSerum is blood plasma with the blood clotting proteins removed. Serum is prepared by removing blood from the subject, allowing the blood naturally to form a blood clot, and then using a centrifuge to remove the red blood cells and the blood clot. The blood clot takes the form of an indistinct clump.Mentioned in: AIDS Tests, Hyperlipoproteinemia, Hypocalcemia, Serum Sickness, Vitaminsse·rum, pl. sera, pl. serums (sēr'ŭm, -ă, -ŭmz ) Avoid the colloquial or jargonistic use of this word in the sense of 'any biologic agent' ("allergy serum") or 'any injected drug' ("truth serum").1.
