Why do I need urine potassium test?

ANSWER

Your doctor may do it if your potassium was checked from a blood sample and your results showed something may not be right. A second test with urine can help her narrow down the reasons.

Your doctor also may order the urine test if:

  • You take diuretics or are on dialysis
  • You have kidney or adrenal gland problems
