Potassium deficiency, how come the labs don't show it? What are all the tests that need to be done to find out if I have low potassium if my electrolytes are normal on the labs? Help ......

If there is hypokalemia, then it can be seen in the laboratory biochemical electrolytes, but if a large number of potassium ions are transferred from intracellular to extracellular, there may be intracellular potassium deficiency, which can not be detected by the laboratory, but generally as long as the potassium ions in the serum are normal, then there will be no symptoms of hypokalemia.
