Abstract
A method for the analysis of at least two analytes in a liquid sample, in which a substrate is provided wherein at least two different types of capturing molecules are immobilized on the substrate and wherein each type of capturing molecule has specific affinity for an analyte. The sample is contacted with capturing molecules, wherein for at least one analyte to be analyzed contact is induced between the capturing molecules and a labelled detection molecule with specific affinity for the analyte, and for at least one another analyte to be contact is induced between the capturing molecules and a labelled version of the analyte. A detectable signal is measured from the labelled detection molecule and the labelled analyte on the substrate, wherein the concentration of the labelled analyte is adapted to the concentration of the analyte in the sample.
