I also had very high levels of sodium/potassium levels, but mine were measured on my hair test. However, my aldosterone levels were low and my cortisol test also was very low.
Your test results mean that your body is under intense stress, which makes the adrenals release more sodium into your body. Your sympathetic nervous system is dominant which is where that panicky feeling comes from. Basically your body is stuck in fight or flight, and completely exhausted from it.
