to a given amount of another substance.
The strength of a solution or the concentration of a substance (as an
antibody) in solution as determined by titration
Standard of strength per volume of a volumetric test solution.
*agglutination titer: The highest dilution of a serum that will cause
clumping or agglutination of the bacteria being tested.
*antibody titer: A measure of the amount of antibody against a
particular antigen present in the blood. One use is in detection of
antibodies against herpes simplex and Epstein-Barr viruses. Researchers
believe that any elevated antibody titers may indicate a decrease in
lymphocyte activity as the result of the stress response or other condition,
as these viruses are generally controlled by T lymphocytes. This titer is
also useful in following the course of many acute infectious diseases. A
rising titer usually indicates the disease is present and the body is
reacting to the specific antigen.
