Abstract:
1. An immunosensor system for blood with reduced interference, comprising: an immunosensor for blood samples that generates a signal based on the formation of a sandwich on a sensing surface between a first immobilized antibody to a target analyte, the target analyte, and a labeled antibody, wherein the sensing surface of said immunosensor further contains a second immobilized antibody covering at least a portion thereof that forms an immunocomplex between an endogenous or exogenous protein that is in the sample and that is not the target analyte, wherein the endogenous or exogenous protein is not labeled and does not contribute to the signal, and wherein the first immobilized antibody and the second immobilized antibody are present on the same region of the immunosensor.
