Abstract
Disclosed in an integral multilayer analysis element comprising in order, first at least one reagent layer and second a porous spreading layer laminated on a light-transmissive water-impermeable support, wherein a fluorine-containing surfactant is incorporated at least in said spreading layer. The element is especially suitable for clinical examination of an aqueous liquid sample of a human humor such as blood, lymphatic liquid, saliva, urine, etc. By the incorporation of the F-containing surfactant, the spreadable area can be controlled over a broad range of the spotting amount of a sample liquid without interfering with the metering function of the spreading layer.
