only band 31 and 41+, false positive?

I just found out the igenex test report which I did it 5 years ago,the igm show positive,but only band 31 and 41,I just read some information from igenex website and it said if only this two band got +,it could be false positive,and need to do only band 31 to confirm it.anyone have this experience??

It's not clear why Igenex holds that position about band 31. There are quite a few references showing band 31 is a major protein for Lyme, and if I'm reading right, it's Lyme specific.


Band 31:

www.ncbi.nlm.nih.gov/pubmed/9440203


www.ncbi.nlm.nih.gov/pubmed/8406878


www.ncbi.nlm.nih.gov/pubmed/8005219


www.ncbi.nlm.nih.gov/pubmed/10030131

It really makes no sense as to why anyone would say that band 31 isn't specific for Lyme, unless they are being pressured to promote misinformation or are simply uneducated. There are Pubmed articles that show otherwise!!
