Antinuclear Antibody Index

Featured: Antinuclear Antibody Test Main Article

Antinuclear antibodies (ANAs), unusual antibodies that can bind to certain structures within the nucleus of the cells, are found in patients whose immune system may be predisposed to cause inflammation against their own body tissues. ANAs are indicative of the potential presence of an autoimmune illness.
