A titer (or titre) is a way of expressing concentration. Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative. The titer corresponds to the highest dilution factor that still yields a positive reading. For example, positive readings ...
(ti´tәr) the quantity of a substance required to react with or to correspond to a given amount of another substance. agglutination titer the highest dilution of a serum that causes agglutination (clumping) of microorganisms or other particulate antigens.
Type: Term Pronunciation: tī′tĕr Definitions: 1. The standard of strength of a volumetric test solution; the assay value of an unknown measure by volumetric means.
Titer: The degree of dilution of a substance such as an antibody, reflecting the strength of the solution. The English spell it 'titre,' French for 'title,' derived from the Latin 'titulus,' an inscription or label. The 'titre' was evidence of the fineness of an alloy of gold or silver.
A quantitative measure of the concentration of an antibody or antigen in blood serum; determined in principle by making serial dilutions of serum and identifying the highest dilution at which the antibody or antigen can still be detected.
A laboratory measurement of the amount (or concentration) of a given component in solution.
[n] - the concentration of a solution as determined by titration
concentration obtained by titration; the reciprocal of a measurement of biological activity determined by finding the dilution of an unknown (e.g., antigen-specific antibody in an antiserum) that shows the defined end-point; always expressed as a whole number
The detection of antibodies in blood through a laboratory test.
The detection of antibodies in blood through a laboratory test. 
titre noun the concentration of a solution as determined by titration
The reciprocal of the highest dilution of serum that gives a reaction in an immunological test.
the quantity of a substance required to produce a reaction with a given volume of another substance, or the amount of one substance required to correspond with a given amount of another substance.
the measure of the level of antibodies in blood
