I was looking for a specific explanation of a report for one of our members, and while I didn't find the answer I was looking for, I ran across this paper.
/www.lymedisease.org/wp-content/uploads/2014/08/Image13-link-pdf-brenner.pdfI scanned through it and decided this is an excellent tutorial for recognizing when your test may be showing positive when your doctor may be saying negative or inconclusive.
Good thing to study and become familiar with.
It is a '96 paper, and a bit old, but I think the information is still valid.
