Abstract
The invention concerns a test element for carrying out an immunological sandwich test for determining an analyte from a liquid sample containing a reagent zone or conjugate zone which contains a conjugate of an analyte binding partner and a label which can be detected directly or indirectly by visual, optical or electrochemical means (e.g., an enzyme, fluorescent or direct label, etc.) wherein the conjugate can be dissolved by the liquid sample, a detection zone which contains a permanently immobilized (i.e., which cannot be detached by the liquid sample) binding partner for the analyte or for complexes containing the analyte; and a control zone which contains a permanently immobilized binding partner for the conjugate of analyte binding partner and label characterized in that the control zone additionally contains one or more permanently immobilized binding partner(s) for the analyte or for complexes containing the analyte.
