Interpretive Guidelines:

Interpretation requires clinical correlation. In the hypokalemic patient, a spot urinary potassium greater than 20 mmol/L suggests that the kidney may be the source of potassium loss or that the loss may be acute. Random excretion is variable and must be correlated with the patient's diet, acid-base balance and state of hydration. Significant diurnal variation (output greater at night) can exist. Results may be useful in conjunction with other tests.

There are no established reference ranges for Random Urine Potassium.
