Antinuclear Antibodies (ANAs)

Antinuclear antibodies (ANAs) are proteins made by the immune system that mistakenly target the body's own cells, particularly the nucleus, which contains genetic material. Their presence can indicate autoimmune diseases, where the immune system attacks healthy tissue. Common conditions associated with ANAs include lupus, rheumatoid arthritis, and scleroderma. A blood test detects ANAs, but a positive result alone does not confirm a disease; it requires further evaluation by a healthcare professional. Understanding ANAs is important for diagnosing and managing autoimmune disorders effectively.
