I have a Question about those of us who are RA neg.
I am wondering why it is that most people with SLE have a pos RA factor. I have SLE and do not have a positive RA factor. Can this be common with SLE? I have wondered about that for years. I asked one of the American Lupus Foundation Chapters about this and the lady, basically laughed at me and told me that that is because it is a totally different illness. Could anyone explain this to me and if it is common to have SLE with a pos ANA but a neg RA factor? Hugs, Kathleen
