If this does not get you to the presentation, can just go to youtube.com and type in "Autonomic Response TEsting" and look for Sept. 15 presentation. The last 10 min. or so really get into the how/whys of the testing.
This presentation was given by Dr. K (MD) on Sept. 15. It has a lot of interesting information in it no matter if you are interested in looking at an out-of-the-box treatment/diagnosis approach or not. Do not believe he mentions in the video, but I believe he does blood work to confirm all the diagnosis as well.
The very end also has some really interesting info. when questions are asked.
My son has been seeing a doctor in his office for 3 years now and I learned more about how/why they take the approach that they do. My husband and I also started going to the same doctor this year and are very pleased with diagnosis/treatment (even if some of it hurts! i.e., injections).
It seems that you can never have enough information in which to treat the chronically ill.
Best wishes on healing!
