There are two different labs performing this test. One in Wisconsin USA, (Neuroscience/Pharmasan labs) and one in Germany (I think so..name?).
I'm no expert on the USA version, but the i-spot is kinda odd, as it doesnt measure "bands" or antibodies. It provides you with two pieces of information:
1)It measures a reaction/strength of your bloods T cells subjected to their own culture(s) of lyme bacteria to somehow determine pos or neg. Apparently they proved anyone with active lyme has weak T cell strength. You have to have enough T cells for this test to work.
2)It also tells your T cell level / quantity compared to some range they determined is accurate among 400 non lyme people. The longer one has lyme, the less T cells in quantity you might have.
In the case of to low # of T cells, this means lyme itself is a possibility among only a few other things, some most likely still unknown.
