Sodium

Usually, a sodium urine test doesn't require any kind of special preparation. However, you should avoid certain medications or food that could possibly hamper your sodium levels.

Low sodium levels could be a sign of hyponatremia, i.e., low blood sodium or fluid retention. Whereas, high levels can indicate excessive sodium intake, dehydration, or renal issues.

Urine is usually collected for 24 hours in order to perform a sodium urine test. All urine produced during a 24-hour duration is collected in a container to be examined.

A sodium urine test is completely risk-free and non-invasive. There isn't any discomfort or negative effects because it just entails collecting urine.
