antibody titer

the concentration of antibodies circulating in the bloodstream of an individual. A rising titer usually indicates the body's response to antigens associated with an active infection.

antibody titer

The amount of a specific antibody present in the serum, usually as a result of an acquired infection; titers for IgM usually rise abruptly at the time of infection–acute phase and fall slowly; during the 'convalescent' phase, IgG ↑ and is elevated for life. See Seropositivity.

antibody titer

The concentration of a specific antibody in plasma. Antibody titers are used to establish the diagnosis of some infectious diseases: a rising titer indicates a recent exposure to a specific infectious antigen.
