Abstract

The present invention concerns a method for the determination of an analyte in a sample liquid using a metal complex capable of luminescence as an analyte-specific marker group for the production of a measuring signal in which an unspecific metal complex is additionally added as an interference elimination reagent which has a structure that is chemically related to the marker group.
