ANA Antinuclear Antibodies (ANA)
Quick Explanation
Antinuclear antibodies target components of the cell nucleus and are an important screening test when autoimmune diseases like lupus are suspected. A positive value alone is not a diagnosis, since ANA can also be detectable in many healthy people and other conditions.
🔍 Possible Causes
Value too high — possible causes
- ·Systemic lupus erythematosus
- ·Other autoimmune diseases (e.g. Sjögren's syndrome)
- ·Can also occur in healthy people at low titer
This list shows possible causes — not a diagnosis. Only your doctor can correctly interpret your result.
