Potassium enters the body via oral intake or intravenous infusion, is largely stored in the cells, and is then excreted in the urine. The major causes of hyperkalemia are increased potassium release from the cells and, most often, reduced urinary potassium excretion ( table 1 ). Webwhen hyperkalemia occurs in the absence of a clinical risk factor. Fist-clenching, application of a tight-fitting tourniquet, or use of small-bore needles during phlebotomy can all cause pseudohyperkalemia. Mechanism of pseudohyperkalemia.
