Hoë kalium in bloedtoets. What does high potassium mean?

Upper limit of potassium (k) test (na) (normal referent values) is 5.1 mmol/L (or 20 mg/dl).

Hyperkalemia can have serious, potentially life-threatening effects on the body. A gradual increase in potassium, as may occur with chronic renal failure, may be better tolerated than a sudden increase.

Slightly higher than normal potassium levels may be well tolerated by some persons with chronic renal failure.
