Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A 24-hour urine sample is required to measure sodium levels in the urine.
Test Time:
Test results are typically available within a few days after collecting the 24-hour urine sample.
Test Normal Range:
The normal range for sodium in a 24-hour urine collection can vary but is usually between 40 and 220 millimoles per day (mmol/day).
What is the Test:
The sodium urine 24-hour test measures the total amount of sodium excreted in the urine over a 24-hour period. It helps assess how the kidneys are handling sodium, an important electrolyte in the body.
Test Procedure:
A healthcare provider will provide you with a large container for collecting urine over a 24-hour period. On the first day, the first urine void in the morning is typically discarded. You collect all subsequent urine voids in the container provided over the next 24 hours. The container is kept in a cool place during this time. After 24 hours, the container is returned to the lab for analysis. The laboratory measures the total sodium content in the collected urine.
When to Take the Test:
This test is typically ordered to evaluate sodium excretion in individuals with certain kidney or electrolyte disorders.
Who Should Take This Test:
People with kidney disease, high blood pressure, or other conditions affecting sodium balance may have this test ordered by their healthcare provider.
Precautions for Exceptional Cases (Pregnancy, etc.):
There are no specific precautions related to pregnancy for this test. However, pregnant individuals with kidney-related issues may have their sodium levels monitored for overall health reasons.
