A novel material and device useful in solid-phase binding assays to determine the presence or amount of an analyte in a test sample, particularly antigens, antibodies, or other ligands or DNA segments. The material and device comprises a reaction site having procedural controls and an analyte binding area capable of being simultaneously contacted by the sample and reagent used in the performance of the assay. The procedural controls and analyte binding areas operate to provide readable results as to the presence or absence of analyte and simultaneously verify the assay procedure and therefore the assay result.

A solid-phase assay device for use in a binding assay to determine the presence or amount of a specific binding analyte in a fluid sample, comprising a reaction site having: a first control area including means for displaying a first detectable response if the assay results are invalid, a second control area including means for displaying a second detectable response indicative of a valid assay result, and an analyte binding area including means for displaying a third detectable response in the presence of label indicative of the presence or amount of the analyte in the fluid sample, substantially oriented in a single area so that each of the first control area, second control area and analyte binding area is capable of being substantially simultaneously contacted by the fluid sample and by reagents used in the assay without the need for performing a separate control assay, wherein said second and third detectable responses, when present, are separately distinguishable and together form an interactive symbol.
