What Is a Urine Salinity Test?

A urine salinity test checks the amount of sodium/Chloride in a sample of your urine to see whether it’s at a normal level. Salt intake is an important factor in the control, or lack of control, of hypertension and of congestive heart failure. Having too much or too little sodium/chloride can mean there’s an issue with your kidneys or perhaps another health matter. The salinity urine test helps to figure out whether your kidneys are working as they should to remove sodium.
