This test is used to evaluate the level of sodium in the urine. It aids in the diagnosis of disorders related to sodium imbalance in the body. This test is also useful for the determination of cause of kidney damage in patients suffering from kidney disorders. Sodium is a vital electrolyte and functions to coordinate muscle and nerve functions. It also plays central role in maintaining the amount of body fluids and too much fluid can lead to edema while less fluid causes dehydration.
