Lani, anyone? ,Elevated ANA titer, have questions?

[Soccermom]

Is anyone knowledgeable in the area of ANA (anti-nuclear antibody) titers and its relationship (or lack thereof)to being Her2+?
I am being checked for inflammatory disease and the only test that came back high is my ANA titer(160). The Doc suggested that I do further testing to rule out Lupus, Scleroderma or other auto- immune conditions. Was wondering if this elevation might have something to do with having had Herceptin, which is a monoclonal antibody, and could therefore assume the reading is "normal" for my body.

Thanks for any andall info!
