Abstract
An immunochemical process and the reagents for measuring hapten by using an agglutination inhibition reaction, anti-hapten antibody sensitized particles and a hapten-carrier conjugate which is capable of agglutinating said particles.
Claims4
An agglutination inhibition immunoassay for measuring the presence or level of a hapten in a sample comprising
- (a) mixing with said sample a quantity of antibody-sensitized particles, said antibody being reactive with the hapten under assay,
- (b) mixing with the mixture resulting from step (a) a quantity of antigen-sensitized particles, said antigen being reactive with said antibody;
- and
- (c) correlating the agglutination or lack thereof with the presence or level of said hapten in said sample.
