Immunological Test Element with Improved Control Zone

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