A method and an apparatus for measuring glucose level in the body fluid of a subject, typically blood glucose level, by measuring impedance of a body tissue, with two pairs of electrodes, two electrodes for injecting current into a body tissue and two electrodes for detecting the ensuing voltage of the body tissue. The body tissue is typically a sub-dermal or sub-cutaneous tissue. The measured impedance of the body tissue is used to correlate with directly determined glucose levels to determine the glucose level from the measured impedance. It is thus possible to determine body fluid glucose levels in a reliable and reproducible manner.

Medical apparatus for diagnosing of a diseased condition of the skin of a subject. The apparatus comprises an electrically conducting probe including a plurality of electrodes, each electrode comprising a plurality of micro-needles, wherein each electrode comprises a base substrate, said micro-needles being integrally formed with said substrate and arranged in a laterally spaced relationship apart from each other and having a length being sufficient to penetrate the stratum corneum, said micro-needles being arranged with an at least partially oblique shape. Furthermore, the present invention relates to an electrode for use in the device, arrays of micro-needle and method for the diagnostics of biological conditions using impedance measurements. The diagnostics is in particular related to cancer, and preferably skin cancer, wherein skin cancer is a basal cell carcinoma, a malignant melanoma, a squamous cell carcinoma, or precursors of such lesions.
