My neurologist ordered a full hormone and nutrient test for me also. My thyroid was low and I was borderline Vit D deficient. I took supplementation for the Vit D for a month to get the level up to normal (with a smaller maintenance dose) then started the thyroid meds (about 3 weeks ago). I still have a lot of typical PCS symptoms but my energy level is up and I feel better mentally/emotionally. Every little bit helps. The doctor called the panel the neuroscience panel-I think that is the name of the lab that did it. He said if my insurance didn't cover it the test would have cost ~$230. I don't know if that is a lot or a little but the panel covered all the hormones Mike mentioned plus some others. Hope this is useful to some of you.
