A system for performing at least one impedance measurement on a biological subject, the system including a measuring device having a first housing including spaced pairs of foot drive and sense electrodes provided in electrical contact with feet of the subject in use, a second housing including spaced pairs of hand drive and sense electrodes provided in electrical contact with hands of the subject in use, at least one signal generator electrically connected to at least one of the drive electrodes to apply a drive signal to the subject, at least one sensor electrically connected to at least one of the sense electrodes to measure a response signal in the subject and a measuring device processor that at least in part controls the at least one signal generator, receives an indication of a measured response signal from the at least one sensor and generates measurement data indicative of at least one measured impedance value and a client device in communication with the measuring device, the client device being adapted to receive measurement data allowing the client device to display an indicator associated a result of the impedance measurement.
