In brief: Age and gender

Positive ANA test is commoner in older people and women.
Up to 25% of the people may have positive ANA test at some time or the other. Only 0.1-0.15% of the population has systemic lupus.

In brief: ANA is not Lupus

The antinuclear antibody (ANA) is a blood test.
We all have an ana, but most of us have this below the level we see in people with lupus and other conditions. Blood bank studies suggest that ~ 5% + or - of healthy people have a + ana. Can you have a + ANA and never get lupus? - yes. Some will progress to lupus but there are many other causes of a + ANA which need to be considered.
