Core Tip

Core Tip: Pseudohyperkalemia in patients with chronic renal failure has been rarely reported, as an elevated level of potassium is typically correlated with impaired renal function. Herein, we studied pseudohyperkalemia caused by thrombocythemia in a patient suffering from chronic renal failure. A review of the literature is also provided to improve the overall awareness of the phenomenon in these patients. To our knowledge, our study was the first related literature review, and is the first to report the therapeutic process and outcome for an essential thrombocythemia patient with chronic renal failure.
