My son has had 2 endocrinologists who have sent tests to different labs and each lab had different range of what was good. I think it can be hard to get "good level" information from anyone other than the dr. who ordered the labs. With that said . . . the range we were given for sodium was 137 - 147 and Potassium at 4.1 - 5.3. We don't have the other things tested (his dr. tests ACTH, 17 OHP, and renin) Hope that helps.
