When the conductivity of the urine test is low, it means that the concentration of urine is low. Low conductivity may be caused by drinking too much water, because drinking more water will lead to low solute content in the urine, so it will lower the conductivity. It may also be caused by abnormal renal tubular function. When the renal tubular function is abnormal, the reabsorption function will be abnormal, and abnormal reabsorption will cause the concentration of urine to be low, which in turn will lead to a low conductivity of the urine test. In addition, it is also caused by the ions and inorganic salts excreted in the urine, which may be a manifestation of kidney disease. If the patient has a low conductivity in the urine test, it may be caused by the amount of water consumed in the light, but in the heavy case, it will make the kidney disease, so further examination should be done to clarify the diagnosis to avoid delaying the disease.
