ABSTRACT:
An immunoassay device and assay to detect an antigen, such as PSA, in a biological sample. The device comprises a solid support having multiple reaction zones containing capture antibodies directed to the antigen. Exposure of a test sample to a mixture of incubation antibodies with known and different concentrations prior to exposure to the capture antibodies in the reaction zones facilitates determination of a range of concentrations of the antigen.
