Antinuclear Antibodies IFA (ANA-IFA) Blood Test
The test for antinuclear antibodies (ANA) is done to help diagnose if you have an autoimmune disease. Antinuclear antibodies are found in individuals whose immune system can not distinguish between their healthy cells and virus and bacterial cells. Your body will produce proteins that attack your healthy cells when this happens. These proteins are also referred to as antibodies.
Redness and swelling, known as inflammation, occurs when the proteins attack cells in the body.
Antinuclear antibodies can be found in many autoimmune diseases, including:
- Rheumatoid Arthritis
Symptoms of autoimmune diseases that antinuclear antibodies can cause include:
