How the Test will Feel The test involves only normal urination. There is no discomfort. Why the Test is Performed The test is often used to help determine the cause of an abnormal sodium blood level. It also checks whether your kidneys are removing sodium from the body. It may be used to diagnose or monitor many types of kidney diseases. Normal Results For adults, normal urine sodium values are generally 20 mEq/L in a random urine sample and 40 to 220 mEq per day. Your result depends on how much fluid and sodium or salt you take in.The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test result. What Abnormal Results Mean A higher than normal urine sodium level may be due to:Certain medicines, such as water pills (diuretics) Low function of the adrenal glands Adrenal glandsThe adrenal glands are two small triangle-shaped glands in the upper abdomen.
