Dry analysis element for quantitative analysis of analyte contained in whole blood

摘要

A dry analysis element for the quantitative analysis of an analyte contained in whole blood comprises a layer exhibiting volume filtration function and a detection layer. The layer exhibiting volume filtration function is made of a cloth selected from microfibrous cloths each having an average fiber diameter of from 0.1 to 10 mu m or a napped cloth having an average of from 1 to 30 mu m. In a first preferred embodiment, the layer exhibiting volume filtration function is composed of a non-woven cloth having a density of from 0.01 to 0.2 g/cm3 and made of fibers each having an average fiber diameter of from 0.2 to 10 mu m. In a second preferred embodiment, the layer exhibiting volume filtration function is composed of a napped cloth having a fiber density per cm2 of from 7.0x103 to 8.2x106, each of the napped fibers having an average diameter of from 1 to 30 microns and an average nap length of 0.5 to 5.0 mm. In a third preferred embodiment, the layer exhibiting volume filtration function is composed of a cloth having a porosity of from 45 to 70% and made of micro filaments each having an average filament diameter of from 0.1 to 7 mu m.
