A system is provided for an integrated circuit package including a leadframe with a lead finger. The current sensitive device comprises a first electrode foil, a second electrode foil and a PTC conductive layer physically laminated between the first and second electrode foils. A test device communicates with the data collection device to store test data concerning the component in the data collection device. By reusing existing management server infrastructures, capital expenses are also reduced. The worker servers are coupled to the queue serer and the mapping server. In preferred embodiments, dry body weight is determined by comparison to the bioimpedance values of normal subjects or by monitoring changes in bioimpedance during dialysis.
