Do you get the serum test done through the same place as the urine test?
I also had an interesting thing happen with the hair analysis tests. From the one I had done in Nov, to this latest one- Sodium/potassium has flip flopped. What Wilson says (ARL lab), is that retests in people can look like they are getting worse instead of better, but it means metals are being eliminated. With adrenals, it can be a change with sodium/potassium because of eliminating toxic copper.
