A positive ANA (Antinuclear Antibody) indicates the presence of autoantibodies that target the body's own cells' nuclei. It suggests an autoimmune response or underlying health issues.
What diseases cause a positive ANA?
Positive ANA is associated with autoimmune diseases like lupus, rheumatoid arthritis, Sjögren's syndrome, and systemic sclerosis, among others.
What cancers cause a positive ANA?
Certain cancers, like breast, ovarian, and lung cancer, can sometimes result in a positive ANA, but it's not a definitive cancer diagnostic tool.
Is ANA positive serious?
A positive ANA is a marker rather than a diagnosis. Its seriousness depends on the underlying cause, which could range from mild to severe autoimmune diseases.
