The Sodium Urine Test evaluates sodium levels in the urine by averaging 24 hours worth of samples. The test can be useful in determining the cause of a sodium imbalance. It is also useful for patients with kidney conditions to determine the cause of damage. The Sodium Urine Test requires a 24-hour urine sample. The lab will provide a collection container and the patient will be instructed to collect all urine for a 24-hour period. Specific directions will be provided by the laboratory. Upon completion of the process, return the sample to the lab for processing.
