Here's your answer -- she gave me permission to pass it on. Hope it helps put your mind at ease.
He surely does use Igenex. He does only their basic pretty inexpensive tests for lyme. He uses either quest or labcore for co-infections. And does the CD57 test thru labcore (the only lab that does it correctly).
I'll sum up his philosophy. Lyme is a clinically diagnosed disease. Sure, testing is important but he tests for a lot of things besides lyme...stuff like Hepatitis, low B-12, etc..... He doesn't do a lot of expensive testing for lyme because of this. He uses lab tests to support a dx and will ultimately treat for EVERYTHING known to be involved with lyme, like Bartonella, Babesia, Erlichia, Mycoplasma, Chlamydia P....etc. if he thinks you have lyme. Lots of these get treated in combo, but they get treated. He generally leaves no stone unturned. Once treatment begins, he monitors your response closely and goes from there.
