Abstract: A measuring arrangement for in-vivo determination of the lactate concentration in blood by means of electrochemical impedance spectroscopy, comprising a substantially flat shaped probe having a longitudinal extension, a transverse extension and a thickness, wherein the longitudinal extension and the transverse extension of the probe are each a multiple of the thickness of the probe, an analyzer circuitry connected to the probe, and communication means connected to the analyzer circuitry for transferring data via a WPAN, wherein the substantially flat shaped probe is arranged at an edge of the measuring arrangement, so that the probe, during operation of the measuring arrangement, faces the animal or human body to be examined, in such a manner that the probe is arranged with its longitudinal and transverse extensions approximately parallel to the surface of the body to be examined, a wristband therefor, and a method for the operation thereof.
