What is an
ANA Blood Test?

Our Antinuclear Antibodies Blood Test sees whether you have auto-antibodies (which attack your cells) to help diagnose several autoimmune conditions, including lupus, rheumatoid arthritis, and Sjögren's syndrome.

What can I learn
from this test?

If are you experiencing symptoms, our test can help confirm if you have an autoimmune disease. However, a diagnosis is unlikely to be given from antibodies alone, as antibodies can be raised even if you have no evidence of disease.

What causes
autoimmune conditions?

Autoimmune conditions happen if your immune system mistakes your body's cells as foreign cells and starts attacking them. Usually, your immune system is constantly looking for foreign bodies and will send out an army of fighter cells to attack them. However, if you have an autoimmune disease, your immune system mistakes parts of your body, like your joints or skin, as foreign. In this instance, it releases proteins called autoantibodies that attack healthy cells. Read more about this in our blog: Autoimmune disease – why one often follows another.

Antinuclear antibodies Antinuclear antibodies are produced by the immune system when it fails to distinguish between its own cells and foreign invaders such as bacteria and viruses. Antinuclear antibodies attack proteins inside the body's own healthy cells and cause symptoms such as inflammation, joint pain and fatigue.
