Clinical research has demonstrated that it is not necessary to completely annihilate the various bacteria involved in Lyme disease. In the same way that no doctor keeps testing to determine if every single Strep bacteria is gone, because health is restored and the bacteria become irrelevant. It is the premise of American Biological Medicine to always address the damaged tissues of the body in their entirety at every stage of the treatment of people with Lyme Disease. So Pre or Post-Lyme is handled virtually the same. Until the integrity of the body has been addressed the bacteria will always come back. I encourage you to read the many relevant posts on my blog
