The urine potassium test measures the amount of potassium excreted in a urine sample. Potassium is an essential electrolyte involved in maintaining normal muscle and nerve function, heart rhythm, and overall fluid balance in the body.

This test is used in the assessment of electrolyte balance and may help in evaluating kidney function and disorders affecting potassium regulation.

Patients are advised to contact the laboratory for specimen collection instructions prior to booking an appointment.

The findings related to these particular clinical tests are a general guide and do not cover every possible scenario, this is because every patient is unique and these results only have true clinical significance when combined with the patient’s full medical history, a physical exam, and other diagnostic findings.
