The Western Blot is confusing. Those with chronic Lyme have a hard time testing positive as it's looking for antibodies that the Lyme infection keeps the body from producing by hiding inside of our cells, joints, tissues and other places.
here is the site that I use to help interpret them:
www.reocities.com/HotSprings/Oasis/6455/western-blot.txtAn IgM result means that you have an active infection. It once was thought to mean an 'early' infection, but has since been revised. IgG means that the infection is at a later stage.
The more +'s you have beside a number, the stronger the reaction.
IND means indeterminate - not negative, but not quite strong enough to be "fully positive". But it means that you reacted on those bands and should be considered, especially when they are Lyme specific bands.
A "Lyme specific band" means specific for Borrelia Burgdorferi, sensu stricto - Lyme disease in the strictest sense. There is only
one on the over 300 known strains of Lyme that is considered Bb, ss.
Bands 18 & 41 (whether in IgM or IgG) are indicative of the tail of the bacteria, which can cross react with other Spirochetal bacteria such as Relapsing Fever, Pintas and Yaws, and Syphilis.
Band 58 is thought to be Borrelia Afzelii (a European strain if I remember correctly).
Band 39 refers to BmpA - Bacterial Membrane Protein "A" and is specific for Lyme.
Band 30 is OspA - Outer Surface Protein "A".
So you've had one band for sure that is Lyme specific turn up IND- which as I said, means that it's a weak positive is all. That can only be from Lyme bacteria, so you have Lyme - especially when you consider the other lab evidence.
