I haven't forgotten your negative test and I have news for you!
Yesterday, I spent all afternoon at the Belgian Senate to attend a round table about Lyme Disease. I got an answer on whether a negative Borrelia Burghdorferi Elispot LTT per se means that you are negative for LD.
The answer is no!!
There are 2 things that can cause a false negative: the main reason is that there were simply not enough lymphocytes present in the blood they tested. The other reason is that you might have a not so common strain of Borrelia. In fact, the test is called Borrelia Burghdorferi Elispot LTT, but they could let drop the Burghdorferi, cause they are measuring interferon gamma. My dr said though that a false negative can be caused by a not so common strain of Borrelia. What follows is my own remark: you live in Australia, so...
I hope this gives you some hope on not being crazy (just joking about what you posted earlier, I don't want you to think I'm making fun of you).
D-Day is coming close, isn't it, your first llmd visit???
Let me know what he says about this!!
