What does an ANA Panel check for?
An ANA test looks for antinuclear antibodies in your blood. If the test finds antinuclear antibodies in your blood, it may mean you have an autoimmune disorder. An autoimmune disorder causes your immune system to attack your own cells, tissues, and/or organs by mistake.
What diseases are associated with positive ANA?
Conditions that usually cause a positive ANA test include:
- Systemic lupus erythematosus.
- Sjögren’s syndrome — a disease that causes dry eyes and mouth.
- Scleroderma — a connective tissue disease.
- Rheumatoid arthritis — this causes joint damage, pain, and swelling.
- Polymyositis — a disease that causes muscle weakness.
What level of ANA is significant?
Titers of 1:80 or lower are less likely to be significant. (ANA titers of less than or equal to 1:40 are considered negative.) Even higher titers are often insignificant in patients over 60 years of age.

- Some medications.
- Having relatives with autoimmune diseases.

What happens after a positive ANA test?
A positive test for antinuclear antibodies (ANA) may assist health care providers in establishing the diagnosis of an autoimmune disease and may help determine the specific type of autoimmune disease that is affecting a patient.
Does fibromyalgia cause positive ANA?
False-positive ANA tests are particularly likely to occur in the elderly. Most of the false-positive ANAs were of low titer, but even a high-titer ANA is not proof of an underlying connective tissue disease. Therefore, not surprisingly, ANA testing is frequently positive in patients with fibromyalgia.
Can you have a positive ANA without having an autoimmune disease?
A negative test for ANA may assist health care providers by decreasing the likelihood that a patient’s symptoms are caused by an autoimmune disease. Some individuals, even those without a relative with autoimmune disease, may have a positive test for ANA and yet never develop any autoimmune disease.
How do I know if I have lupus or fibromyalgia?
