What is ANA?

Antinuclear antibodies (ANA) are a type of autoantibody that is directed against the body's own cell nuclei. They are found in a variety of autoimmune diseases, including lupus, rheumatoid arthritis, and Sjogren's syndrome.

What causes ANA?

The exact cause of ANA is unknown, but they are thought to be produced by the immune system in response to a trigger such as infection or tissue damage. In some cases, ANA may be present in people without any symptoms or signs of disease.

What are the symptoms of ANA?

The symptoms of ANA can vary depending on the underlying autoimmune disease. Some common symptoms include:

* Fatigue

* Joint pain

* Muscle pain

* Skin rashes

* Fever

* Weight loss

* Lymphadenopathy (enlarged lymph nodes)

* Dry eyes

* Dry mouth

How is ANA diagnosed?

ANA is diagnosed with a blood test. The test measures the levels of ANA in the blood. A positive ANA test does not necessarily mean that you have an autoimmune disease, but it may indicate further testing is necessary.

How is ANA treated?

There is no specific treatment for ANA. Treatment is focused on managing the symptoms of the underlying autoimmune disease. Treatment may include medications, lifestyle changes, and complementary therapies.
