Abstract
The present invention is directed to methods for increasing sensitivities of immunoassays. The invention utilizes an acid elution condition that preferentially elute specifically bound immune complexes over non-specifically bound complexes from a solid phase, and designs immunoassay protocols that improve the ratio of specific binding to non-specific binding and thereby improving assay sensitivity. The protocol determines the signal of the labeled immunocomplexes eluted from a solid phase.
