Potassium (24 hour urine test)
We remind you that independent interpretation of test results is not permitted; the information below is provided for informational purposes only.
Potassium, K (in 24-hour urine) is the measurement of the amount of potassium excreted in the urine over a 24-hour collection period. The test provides information about renal potassium excretion and contributes to the assessment of the body's electrolyte balance.
Potassium excretion may vary depending on dietary intake, kidney function, hydration status, and the use of certain medications. The result should be interpreted in the context of clinical data and, where appropriate, together with blood potassium levels and other electrolyte measurements.
Indications
- assessment of renal potassium excretion;
- investigation of electrolyte balance disorders;
- evaluation of the causes of changes in blood potassium levels;
- monitoring patients with conditions or treatments that may affect potassium metabolism;
- assessment of kidney function in certain clinical situations;
- other indications as recommended by a physician.
Procedure
Urine is collected over a 24-hour period in a special container according to the laboratory's instructions. After collection is completed, the sample is submitted to the laboratory to determine the amount of potassium excreted.
