Test Details

A 24-hour urine collection to measure sodium is a test that determines the amount of sodium excreted daily. It helps assess kidney function and monitor sodium imbalances. To perform this test, mark a large container and begin collecting urine after the first urination of the morning. Collect all urine produced over the next 24 hours, keeping it refrigerated. Finish by adding the last urine produced after the 24-hour period. The sample is then sent to a laboratory for sodium analysis. It is crucial to avoid losing any urine and to follow your doctor's instructions regarding fluids and medications.
