This is probably what Ali already posted elsewhere, but I thought I would add it here just in case:
http://igenex.com/Website/#
IgeneX has a new test that can confirm if the #31 is actually from lyme or not. I don't know how long ago you were tested, but some think that IgeneX keeps your sample for a while in case you want more testing done.
I am reading a book called the Lyme Disease Solution written by an LLMD and he says that if you have the #31 w/ #41 that he thinks that it is from lyme and not from a virus.
Doesn't mean anything. Band 41 can be positive for anything with a flagella, like gingivitis. Igenex's own website says the band 31 can positive if other viruses are present, like EBV, to which everyone has been exposed.
Please read my last post re: band 31.
