Web5 Dec 2024 · How Hyperkalemia Is Diagnosed. When your serum potassium level is 5.5 mEq/L or higher, you may be diagnosed with hyperkalemia. 1 The condition can be caused by ingesting too much potassium (eating or … WebTherefore, potassium diffuses out of the cell at a much faster rate than sodium leaks in. Because more cations are leaving the cell than are entering, this causes the interior of the cell to be negatively charged relative to the …
