Hi, ANA is anti-nuclear antibodies. Antibodies are proteins that your immune system makes to fight off bacteria, viruses, and other germs. But sometimes, your immune system can mistake parts of your own body for foreign invaders. It releases special antibodies, called “autoantibodies,” that attack your cells and tissues. . And they can be a sign of autoimmune diseases. Reference Range:
< 1.0 AI Negative
>=1.0 AI Positive
It is generally a sign of an autoimmune disease. It can take a long time to determine if it is an autoimmune disease or just a false positive. Be patient, it is usually a long road to diagnosis. Good luck.
