Thanks for posting the links to all the information that you did. I read it all and printed it out so that I can read and understand it. I received my printed results today. Although I do not fit the Igenex or CDC 'strict' definition of positive, there was more listed than I thought. I looked up all the bands so I could know what the antibodies were to. IGG (all kDa) 18 + 31 IND 41 + 58 ++ 66 + IGM (all kDa) 18 + 23-25 IND 31 IND 39 IND 41 IND all other bands Negative.
