Here is the information abouit Dr. Glen Wilcox (New Mexico) - LINK
I have not spoken to their office but was told that you can call them for a parasite testing kit which the cost is $369 as of this writing. From what I understand he uses a lab outside of the United States who reportedly is good, finding parasites that other labs failed at. Dr. Wilcox does not prescribe drugs, only herbs. If you have used this lab please let us know the outcomes.
Advantage: Test from home, apparently lab is good.
Disadvantage: Treats with herbs only, no prescriptions. Treating doctors may not accept these findings since they are not a 'normal' lab.
Here is what Dr. Wilcox says on the website
