Ahmed Y, Rahman MU, Houston J, Al Jaber E. Reverse pseudohyperkalemia: Verify potassium levels before initiating treatment. Int J Case Rep Images 2020;11:101123Z01YA2020.ABSTRACT
Hyperkalemia is a complex laboratory abnormality. There are varying degrees of true hyperkalemia, pseudohyperkalemia, and even reverse pseudohyperkalemia which must be distinguished from one another. We present a case of reverse pseudohyperkalemia in an elderly male with a hematologic malignancy found to have an elevated potassium level on admission. Both plasma and serum levels were measured, plasma level was high while serum levels were normal, and a diagnosis of reverse pseudohyperkalemia was made. Awareness and increased suspicion result in rapid diagnosis, and prevent overtreatment and iatrogenic complications.
Keywords: Hyperkalemia, Pseudohyperkalemia, Reverse pseudohyperkalemia
