The blood tests are well known to be not indicative either way for the presence of Lyme.
Time is of the essence when it comes to a lyme diagnosis.
To these people, and to this question, I dedicate this page. As I had mentioned above, when lyme is concerned, time is of the essence. The infection can begin to go into the deep tissues within a couple of weeks. And the delay of finding a good doc can make all the difference. If lyme is found quickly, and treated properly, it can be completely cured.
