Abstract
A test element, for example in the form of an immunological test strip functioning according to the sandwich principle, for the fluorophoric detection of one or more analytes in a sample comprising an analyte detection zone and a combined control and calibration zone. The combined control and calibration zone include a fluorophore and binding partners for the specific binding of reagents labelled with a fluorophore. Furthermore, the invention concerns a method for calibrating an analyte-specific measurement signal, a method for determining the concentration of an analyte in a sample and the use of the test element for calibrating a signal generated in the analyte detection zone of a test element.
Claims12
A test element for conducting a specific binding assay, the element comprising an analyte detection zone and a combined control and calibration zone, wherein the combined control and calibration zone comprises a mixture of an immobilized fluorophore and an immobilized binding partner for the specific binding of a reagent labelled with a fluorophore.
