The article presents information about the falsely elevated potassium value also called as pseudohyperkalemia. When potassium levels are falsely elevated by specimen-collection or processing errors, patients can be subjected to medical mistakes with many disastrous consequences. Laboratory managers, pathologists and testing personnel are challenged to consider each of the known factors which can cause pseudohyperkalemia.
