Also known as fluorescent antinuclear antibody (FANA) and antinuclear antibody screen, the anti-nuclear antibody test is an antibody test that helps to detect the autoantibodies found in the blood serum of humans. Anti-nuclear antibodies are produced by an individual’s immune system when it fails to distinguish between self and foreign particles to fight against diseases.

Antinuclear antibodies are a collection of autoantibodies produced by an individual’s immune system when it fails to differentiate between self and foreign particles. The Antinuclear Antibody Test (ANA) is also recognized as a fluorescent antinuclear antibody (FANA) and Antinuclear Antibody screen. Antinuclear Antibody attack the body’s cells. Therefore, these are called antinuclear, as they target the nucleus of cells. They react with parts of the body’s healthy cells and cause symptoms and signs such as tissue inflammation, muscle & joint strain, and fatigue. Antinuclear antibodies test identifies autoantibodies in the blood.
An Antinuclear Antibody Test defines the attendance of an Antinuclear Antibody Test in the blood. If a test detects them in the body of an individual, it could indicate that the person has an autoimmune dysfunction. An Antinuclear Antibody Test is practiced to diagnose autoimmune disorders, such as scleroderma, rheumatoid arthritis, Sjogren’s syndrome (an uncommon disease condition that alters the body’s moisture-making glands), and systemic lupus erythematosus (the most typical type of lupus, a chronic disease affecting various parts of the body including kidneys, blood vessels, brain, and joints).

- Rheumatoid Arthritis
- Systemic Lupus Erythematosus
- Sjögren’s Syndrome
- Scleroderma
