I tested urine of an elderly relative with a conductivity meter. It gives me a very high reading, suggesting extreme dehydration. Yet the same person is testing on serum blood tests with low sodium and potassium. How can this be?
I thought high conductivity indicated too great a concentration of electrolyte minerals and that this would be addressed by increased electrolytes. High conductivity suggests the person needs more plain water, without the electrolytes. How do I resolve that discrepancy?
This person has problems holding onto water and tends to immediately urinate any excess water.
