Service Providers for Spot Urine Sodium (Na)
Spot Urine Sodium (Na) is a test that measures the concentration of sodium in a single urine sample. Sodium is an essential electrolyte that helps regulate fluid balance, blood pressure, and nerve function. This test is often used to assess hydration status, kidney function, and conditions like dehydration, salt imbalances, or adrenal disorders. The result is typically reported in milliequivalents per liter (mEq/L) or millimoles per liter (mmol/L). Abnormal sodium levels in urine can suggest issues such as kidney dysfunction, electrolyte imbalances, or problems with fluid regulation in the body. Results are usually available within a day or two.
