Fasting Required: No

Description: One of the major salts in the body fluid, sodium is important in the body's water balance and the electrical activity of nerves and muscles.

The excretion of sodium varies with dietary intake. There is a diurnal variation of sodium excretion with excretion being greater during daytime than during the night. Decreased levels are seen in congestive heart failure, excessive sweating, diarrhea, pyloric obstruction, malabsorption and primary aldosteronism. Increased levels may be due to increased salt intake, failure of the adrenal glands, diabetic acidosis, salt losing renal disease, diuretic therapy and water deprivation dehydration.

Methodology: Ion Selective Electrode (ISE)

Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
