The new criteria require that the test for antinuclear antibody (ANA) must be positive, at least once, but not necessarily at the time of the diagnosis decision because an ANA can become negative with treatment or remission.
Can inflammation cause positive ANA?
Autoantibodies to cartilage proteoglycan can be measured in several systemic and joint-specific rheumatic diseases including Sjogren’s Syndrome, rheumatoid arthritis, lupus and ankylosing spondylitis [21], suggesting that undetected or preclinical joint inflammation may contribute to ANA positivity.

For patients with a positive ANA, more tests are usually performed to check for other antibodies that can help confirm the diagnosis. This series of tests, commonly called an ANA panel, checks for the following antibodies: anti-double-stranded DNA, anti-Smith, anti-U1RNP, anti-Ro/SSA, and anti-La/SSB.

What cancers cause positive ANA?
Neoplastic diseases may cause positive ANA. Some authors have described that ANA is found in the sera from lung, breast, head and neck cancer patients as frequently as in RA and SLE 3, 4, 5. Chapman et al. 6 has suggested that in breast cancer they may be used as an aid to early diagnosis.
Can obesity cause positive ANA?

How common is a positive ANA?
At a dilution of 1:160, only 5 percent of normal individuals have a positive test for ANA. The 1:160 dilution increases the specificity of the ANA test for the diagnosis of autoimmune diseases.
