Which test assesses sodium levels in urine?

The test that assesses sodium levels in urine is indeed the Sodium Random test. This specific test measures the concentration of sodium in an individual’s urine sample at a random time, providing valuable information regarding the body’s sodium balance and metabolic processes. It is particularly useful in evaluating a person's electrolyte status, kidney function, and overall fluid balance.

In contrast, the other tests listed have different focuses. For example, the Calcium UR Random test evaluates calcium levels in urine, which is relevant for assessing calcium metabolism and detecting conditions like hypercalcemia or kidney stones. The Creatinine CLR 24 Hr measures creatinine clearance over 24 hours, primarily used to assess kidney function rather than electrolyte levels. Lastly, the Protein Urine 24 Hr test quantifies the amount of protein in urine, which can indicate kidney health or disease but does not measure sodium content. Therefore, the Sodium Random test directly addresses the assessment of sodium levels, making it the correct choice.
