1. A medical device, comprising: a measuring interface, located between a device and a measuring site of a patient; one or more electrodes to generate a frequency sweep stimulation signal, positioned at the measuring interface and in electrical contact with a portion of the patient; circuitry to measure total bioimpedance values as a result of the stimulation signal at specific frequencies correlating to the frequency sweep; and a processor system to a quantify a fluid contribution, an ion contribution, and a fat contribution from the measured total bioimpedance values from which a physiological report can be generated, wherein the processor system further identifies whether a measured total bioimpendance is reliable based a non-fluid contribution.
