Any of the testing that is out now is based on outdated information is our biggest problem. It's all based on the immune system being able to respond to the bacteria - and yet we know that Lyme inhibits the immune system, so antibodies/antigens can't be produced in high enough quantities to produce a positive result on the testing.
If you aren't trying to get a positive test for insurance purposes, I would suggest that you see a doctor that can clinically diagnose you and get you started on treatments.
If you do need a positive test so insurance will pay for your treatments, there is some new research (from Dr. Klinghardt, I believe) that a deep muscle massage before testing has had some very good results.
I managed to locate an article on it:
