A single urine sample (clean catch) may be taken at a health professional's office or at home. Urine sodium can be checked in a single urine sample, but it is more often measured in a 24-hour urine sample. Low urine sodium levels have many causes, such as heart failure, malnutrition, and diarrhea. Urine sodium levels are affected by medicines and hormones. Results should be interpreted in context with serum results, paired urine and serum osmolalities. Reference range: No reference ranges quoted for random urine samples due to variability. These can also be measured on acidified urine. The urine sodium level is often low when blood levels are high. Special precautions & notes: In both a random and 24 hour sample, the tests are sodium, potassium and creatinine. Urine sodium levels are often high when blood levels are low. Many medicines and other products also have sodium in them, including laxatives, aspirin, mouthwash, and toothpaste.ĭoctors may look at sodium levels in the blood and urine to see whether conditions or medicines may be causing fluid or electrolyte imbalances. Sodium is found in table salt as sodium chloride and in baking soda as sodium bicarbonate. Results that fall outside of the normal range on urine tests can mean a lot of different things. Most foods have sodium naturally in them or as an ingredient in cooking. sodium: 80290 milliequivalents/24 hours: osmolality: 381,400 milliosmoles (mOsm). Small amounts of sodium are also lost through the skin when you sweat. Aldosterone levels tell the kidneys when to hold sodium in the body instead of passing it in the urine. Sodium levels in the body are partly controlled by a hormone called aldosterone, which is made by the adrenal glands. Most of the sodium in the body is found in blood and lymph fluid. Sodium is also important in how nerves and muscles work. It helps keep the water (the amount of fluid inside and outside the body's cells) and electrolyte balance of the body. Sodium is both an electrolyte and a mineral. A test for sodium in the urine is a 24-hour test or a one-time (spot) test that checks for how much sodium is in the urine.
