What can cause a high potassium level with serum testing (5.6) but shows low on RBC potassium on nutreval? She does have chronic kidney disease and also has a lot muscular cramps of legs etc. RBC magnesium levels are normal. She is however wasting a lot of taurine in urine. This is possibly from intestinal candida. So what is the electrolyte deficiency that would be causing the cramps?
So what is gold standard to know if she is actually low in intercellular potassium or not. Go by serum and disregard the RBC potassium in case of CKD?
Thank you for any insights.
