The present invention relates to a single-use monoanalytical test-strip for the quantitative determination of an analyte in a patient's urine sample, and to a non-invasive point-of-care (POC) device for detecting deficiency and/or overload of an analyte in a patient's body. Furthermore, the present invention relates to a method for quantitatively determining the concentration of an analyte in a patient's urine sample and to a method of detecting deficiency and/or overload of an analyte in a patient's body. The test-strip comprises a substrate which either is electrically insulating or which has an electrically insulating layer applied thereon,- an electrode assembly applied on said substrate or on said electrically insulating layer, if present; and said electrode assembly comprises at least- one analyte-selective working electrode;- one reference electrode for said analyte-selective working electrode and an interface for electrically connecting said electrode assembly to a read out-meter device. Analytes are anions selected from halides, phopshates and sulfates or cations of alkali metals, of alkaline earth metals or of other metals.
