I did a 24 hour urine w/o creatinine and the results came back as follows Creatinine 1.24 H eGFR non African American 52 L and creatinine clearance 71 L. Can you tell me what this means? The reason for the test is because I have a history of hypokalemia and we are trying to find out why. I am on Klor-con 8 er three times a day and my levels stay from 3.1 to 3.2

Summarized question: What causes hypokalemia?
