  • Test element for optically testing biological fluids in clinical diagnostic applications
    Patent number: 5399315
    Abstract: An integral test element for analysis of liquids comprising: a) a spreading layer for uniformly spreading within itself at least a substance of a liquid sample applied to the element; b) a reagent layer in fluid contact with the spreading layer and permeable to a substance spreadable within the spreading layer or to a reaction product of such a substance, the reagent layer having a chemically interactive material which, in the presence of the substance or of the reaction product of the substance, produces a detectable change in the element; and c) a radiation upconversion phosphor layer or crystal for producing an upconverted radiation when excited by visible or infrared excitation radiation from an independent source.
