Just received my Cortisol test results. I had it tested because I considered Seriphos for sleep. But as it turns out Cortisol is not too high but too low. Any help interpreting these results is greatly appreciated. How bad are these values? Should I ask my GP for ACTH testing? Will I need Hydrocortisone? or Pregnenolone? Or should I try supplements first? Or is it pretty common in ME to have these low levels? No skin hyperpigmentation (Addison) Thyroid values tested normal before Thanks.
