What is ANA-Screening, Blot, Profile?
An antinuclear antibody (ANA) test measures the amount and pattern of antibodies in your blood that work against your own body (autoimmune reaction). The body's immune system normally attacks and destroys foreign substances such as bacteria and viruses. But in disorders known as autoimmune diseases, the immune system attacks and destroys the body's normal tissues. When a person has an autoimmune disease, the immune system produces antibodies that attach to the body's own cells as though they were foreign substances, often causing them to be damaged or destroyed
Purpose of Test
An antinuclear antibodies (ANA) test is done to help identify problems with the immune system, such as Rheumatoid arthritis, Systemic lupus erythematosus (SLE), Polymyositis, Scleroderma and Sjogren's syndrome
