The 4-hour urinary sodium (Na) report delivery time refers to the period it takes for healthcare providers to receive and analyze the results of a urine sample specifically to measure the sodium levels. This test is important in assessing the body's sodium balance, which can be indicative of various health conditions such as dehydration, kidney disease, or hypertension.

How our test process works!
The 24-hour urinary sodium test measures the total amount of sodium excreted in the urine over a 24-hour period. It provides insight into a person’s sodium intake and renal function, playing a role in assessing dietary sodium balance, hypertension, and other conditions.
Purpose
- Evaluate sodium intake and its relationship to blood pressure.
- Diagnose electrolyte imbalances.
- Monitor kidney function and conditions like kidney disease or heart failure.
- Guide management of fluid balance in conditions like edema or dehydration.
Risk Assessment
- High Sodium Excretion:
- Increased risk of hypertension, cardiovascular diseases, and kidney damage over time.
- Indicates poor dietary control if excessive sodium intake is habitual.
- Low Sodium Excretion:
- Could signify dietary deficiency, malabsorption, or certain medical conditions like adrenal insufficiency.
Normal Range
- Adults: 40–220 mmol/24 hours (may vary slightly depending on diet and lab standards).
- Results can vary based on dietary sodium intake, hydration, and physical activity.
Interpretation
-
Low Sodium Excretion (<40 mmol/24 hours):
- Possible causes:
- Low dietary sodium intake.
- Dehydration.
- Renal insufficiency or kidney dysfunction.
- Possible causes:
-
Normal Sodium Excretion:
- Indicates normal sodium intake and renal function.
- May need correlation with blood sodium levels and other parameters.
-
High Sodium Excretion (>220 mmol/24 hours):
- Possible causes:
- High dietary sodium intake.
- Salt-wasting conditions (e.g., adrenal or kidney disorders).
- Hypertension risk, as excess sodium is linked to elevated blood pressure.
- Possible causes:
Sample Type
- Sample: Urine collected over 24 hours.
- Procedure:
- Discard the first urine of the day.
- Collect all urine over the next 24 hours, including the first sample of the following morning.
- Store the urine in a provided container, typically refrigerated or kept cool.
