Assay Principle

Latex Immunoturbidimetric Assay

When a certain amount of anti-theophylline antibody is added to a specimen, the anti- theophylline antibody binds to theophylline until it has reacted with all of the available theophylline in the specimen. Next, theophylline -coated latex are added, which react with the residual anti- theophylline antibody, leading to agglutination. Since the extent of agglutination depends on the concentration of theophylline in the specimen, the theophylline concentration can be determined by measuring the absorbance as an indicator of agglutination.
