Re: ANA was postive now after 10 months negat
Yes, ANA titres can fluctuate. The meaning depends on what Autoimmune disease you have. I am just a patient, though so always check with your Dr. I believe that the titre rises in lupus just before or at the start of a flair. In scleroderma, the levels don't seem to correlate to disease activity, so ANA's aren't measured after diagnosis, for the most part. These are just 2 examples.
