Test strip, for the electrical measurement of substance concentrations in body fluid samples, has parallel outer layers with electrodes on their inner surfaces, and an absorbent intermediate layer with a specific reagent at the layers
A test strip for the electrical measurement of substance concentrations in fluid samples, and especially body fluids, having two parallel outer layers (12,14) with a reaction zone between their facing inner surfaces (28) with a defined intermediate layer (16) as an absorbent net or membrane, is new. A test strip for the electrical measurement of substance concentrations in fluid samples, and especially body fluids, having two parallel outer layers (12,14) with a reaction zone between their facing inner surfaces (28) with a defined intermediate layer (16) as an absorbent net or membrane, is new. A working electrode (30) is at the inner surface of one outer layer, and a reference electrode is at the inner surface of the other outer layer. A specific reagent is applied to at least one of the layers.
