Abstract

A system and method for measuring the conductivity level in a urine sample. The system also calculates and displays the electrolyte concentration, and the osmotic pressure. The system further indicates whether or not these levels are low, normal, high or dangerous for the heart. The system comprises a power source, a detection probe for measuring the conductivity level of a given urine sample, and a processing means for calculating and outputting the electrolyte concentration and the osmotic pressure of a urine sample. Such calculations are based on the conductivity level measured in the urine sample. The system also includes a display means for displaying the electrolyte concentration and the osmotic pressure calculated by the processing means.
