What are the acceptable potassium levels in a patient with chronic kidney disea?

3.5 to 5.0-5.5. Generally, the potassium should be kept within normal limits just as for a person without renal disease. Most labs have a normal range of 3.5 on the low end and may be anywhere from 5 to 5.5 on the high end. Potassium is less well eliminated by patients with kidney disease and generally with advanced kidney disease, the potassium intake must be reduced.
