You will want one who is either trained by ILADS (many Naturopaths and some Homeopaths are), are Lyme literate because they have treated many people with these infections, or is willing to learn. ILADS has training seminars that they can attend - or you can help educate them, but they have to be willing and have the time to do a bunch of reading.
You can also ask on here to see if someone near your area (you'll have to let us know where that is) knows of a Holistic doc that is able to treat these infections. The bacteria and the infection is much more complicated than 'normal' infections, so the treatment of them is usually fairly complicated.
As for the forms, it's best to call and ask the doctors office if they have the forms or if you should bring them. Just go to
www.igenex.com/ and click on 'forms and sample requirements" - it will
open and you can then choose "test request forms".
