So, my derm who diagnosed me with discoid lupus from a biopsy called with my bloodwork results. She said that the ANA was barely positive and and anti doublestranded DNA antibody test was also barely positive. Everything else was totally normal. Does this mean it is or is not systemic?? I have looked at what the ANA test is and I understand that one, but I don't understand really what the other test is or what it means.
