You need to have IGENEX labs do the testing. They are most accurate. Labcorp and quest are not sensative. You also might have a co-infection with Mycoplasma Fermentans-Incognius, 70% of Lymes have co-infections with this and Bartonella, Babesia, Brucella. There is evidence this was a biowarfare **** and we are paying the price. I know. You or your parents need to check out www.immed.org and www.ILADS.com. The Fed gov't is denying Lyme is a chronic condition after initial antibiotic. They are lying. Watch videos on Youtube under search "under our skin", about Lyme sufferers and how they are being systematically missdiagnosed. PM me if you want further details. Good luck!
