Abstract: According to an example aspect of the present invention, there is provided multilayer test strip comprising a substrate onto which is deposited an electrode assembly layer comprising a carbon-based working electrode, a carbon-based counter electrode, a pseudoreference electrode, wherein the pseudo reference electrode, the working electrode and the counter electrode, are arranged adjacent to each other in the same plane, contacts for contacting the electrodes directly to a voltage supply, and the test strip further comprises a permselective membrane layer, said electrodes of the electrode assembly layer being electrically separated from one another and said electrode assembly layer being positioned between the substrate and the permselective membrane layer.
