I read somewhere if on abx for about 3 weeks and then take another Western Blot test that is would show up positive if you have Lyme. Can anyone confirm this?
Being on continuous antibiotics will show false negatives. There are theories that once you experience a Jarisch-Herxheimer like reaction from antibiotics such as Rocephin (or other Lyme killing high dose antibiotics) and you test the Western Blot a few weeks after the herxing process then you are more likely to receive a positive test due to the fact that the Lyme spirochete is vulnerable within your system and under attack and your body's immune system is finally reacting. Taking that theory into consideration, you would have to experience the herxing process from high dose abx, such as Doxycycline 300-600mg dose (minimum of 4 weeks is ILADS recommended), to experience this effect.

You are lucky to test positively on any given test such as the ELISA due to the fact that the specific IgM bands that the Labs test for are limited; therefore unreliable. If the initial ELISA test does not show a positive result, then the Lab will not even bother to carry out the Western Blot. Being on a low dose antibiotic will do nothing more than allow the Lyme spirochete to become immune to the abx.. it will actually hasten the bacteria's progression as abx's deplete your immune system giving the bacteria the advantage.
