ABSTRACT:
A method is provided to determine the presence of an analyte in a sample. The method provides an element with a sample application zone, a detection zone, a zone containing immobilized analyte or analyte analogue, a conjugate that has a first bioaffine binding partner capable of a specific binding reaction with the analyte and a first detectable label, and a universal conjugate, which can be detached by liquid and comprises a second bioaffine binding partner and a visually detectable label. The second bioaffine binding partner is capable of a specific binding reaction with the first detectable label. The method also includes contacting the sample application zone with the sample, contacting the sample with the conjugate and the universal conjugate to react the analyte with the and the universal conjugate to form a detection complex, and determining the presence of the detection complex in the detection zone of the element.
