An obsolete treatment of disease with a combination of drugs and serum.

1. Containing or producing both mucus and serum.
2. Pertaining to an exudate or secretion that consists of both mucus and serum or a watery component.

The change of a serologic test from negative to positive, indicating the development of antibodies in response to infection or immunisation.

The development of detectable antibodies in the blood directed against an infectious agent.

Following seroconversion, a person tests positive in tests based on the presence of antibodies

The cultivation of serum.

1. Diagnosis of disease based on antigen-antibody reactions in the blood serum.
2. A diagnosis involving tests on blood serum or other serous fluid of the body.
3. Diagnosis by means of a reaction using blood serum or other serous fluids in the body (serologic tests).

1. A peculiar fatty substance found in the blood, probably a mixture of fats, cholesterin, etc.
2. A body found in faecal matter and thought to be formed in the intestines from the cholesterin of the bile.

An expert in the science of the properties and reactions of serums, especially blood serum.

1. A blood test to detect the presence of antibodies against a microorganism.
2. The branch of science concerned with serum, especially with specific immune or lytic serums; to measure either antigens or antibodies in sera.
3. The branch of medicine concerned with the study of blood serum and its constituents, especially its role in protecting the human body against disease.

A mass or swelling caused by the localized accumulation of serum within a tissue or organ.

1. Lacking an antibody of a specific type in serum; used to mean absence of prior infection with a specific agent (e.g., rubella virus), disappearance of antibodies after treatment of a disease (e.g., syphilis), or absence of antibody usually found in a given syndrome (e.g., rheumatoid arthritis without rheumatoid factor).
2. Showing no significant level of serum antibodies, or other immunologic marker in the serum, that would indicate previous exposure to the infectious agent being tested.

1. Showing a significant level of serum antibodies, or other immunologic marker in the serum, indicating previous exposure to the infectious agent being tested.
2. Showing a positive reaction to a test on blood serum for a disease; exhibiting seroconversion.

Consisting of both serum (clear portion of any body fluid) and pus.

A loss in serological reactivity; may be spontaneous or in response to therapy.

1. The outermost coat or serous layer of a visceral structure that lies in the body cavities of the abdomen or thorax; it consists of a surface layer of mesothelium reinforced by irregular fibroelastic connective tissue.
2. The outermost of the extraembryonic membranes that encloses the embryo and all its other membranes; it consists of somatopleure, i.e., ectoderm reinforced by somatic mesoderm; the serosa of mammalian embryos is frequently called the trophoderm.
