ABSTRACT We describe a patient with hyperkalemia and ECG changes with persistent mild hyperkalemia without ECG changes following treatment. Their hyperkalemia was confounded by the presence of true hyperkalemia due to an acute kidney injury and pseudohyperkalemia due to significant thrombocytosis. T...

This was corroborated by a difference in serum and plasma potassium testing.
