What this test is

What it measures
- Potassium — reflects the amount of potassium excreted in urine
- Aldosterone — sometimes measured alongside to assess adrenal function
- Creatinine — often included to help interpret potassium excretion
What the test involves
You will collect a urine sample, usually over a 24-hour period or as a single random sample, depending on the lab's instructions. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test if they suspect an electrolyte imbalance or a hormone-related condition such as aldosteronism. It can also be used to monitor certain conditions that affect potassium levels, like dehydration or digestive disorders.
