Abstract
A method and composition for detecting and measuring analytes, such as antibodies, which are capable of binding with certain binding partners such as antigens. A homogenous assay is performed in the presence of free unbound antibodies. Such a homogeneous assay testing for specific antibodies is herein possible by defining of test subsets of microparticles having specific antigens thereon which are capable of binding with specific target antibodies. The microparticle suspension also includes at least two calibration subsets of microparticles having a binding partner thereon with at least two known levels of concentration which is capable of binding with human antibodies for the purpose of assay calibration. A verification subset of microparticles is included with another binding partner thereon at a known concentration, capable of binding with anti-human antibodies. This suspension is incubated with a human sample and then is incubated with a tagging component.
