Vancomycin

The Vancomycin assay is a homogeneous particle-enhanced turbidimetric immunoassay. It is based on competition between drug in the sample and drug coated onto a microparticle for antibody binding sites of the vancomycin antibody reagent. The microparticle reagent is rapidly agglutinated in the presence of the anti-vancomycin antibody reagent and in the absence of any competing drug in the sample. The rate of absorbance change is measured photometrically. This is used to determine the concentration of Vancomycin within the sample.
