Abstract:
A chromatographic assay device for detection or determination of an analyte comprising:(a) an opposable component including a sample preparation means for receiving a sample to be assayed;(b) a second opposable component including a chromatographic medium;wherein the first and second opposable components are brought into opposition so as to cause the sample preparation means to apply the sample to be tested to the chromatographic medium so that the analyte is detected by a labeled second specific binding partner bound to the analyte, the analyte in turn being directly bound to a first specific binding partner bound to the chromatographic medium so that the labeled second specific binding partner is indirectly bound to the first specific binding partner through the analyte, the labeled second specific binding partner either being present in the assay device in either the first or second opposable components prior to the initiation of an assay or being added to the assay device during the performance of the assay.
