Abstract
Analytical element for the detection of an agent under analysis, termed analyte, dissolved in an aqueous, proteinaceous liquid. The element has at least two superposed layers, the layers including a spreading layer and a reagent layer. The element can include a support material which is preferably radiation transmissive. To normalize transport of the analyte in and through the spreading layer, the spreading layer contains an effective amount of a surfactant, such as a non-ionic surfactant. Preferably, the amount of surfactant is between about 1% and about 15% by weight of solid contents in the spreading layer.
