Hi, dear.
I have gone through your question. I can understand your concern. Serum potassium level is clinically more important and more accurate. Rbc potassium level has many limitations and interference. So go with serum potassium level.
Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
