In brief: Autoimmune disease

ANA (anti-nuclear antibody) is a blood test used by doctors that indicates the presence of an autoimmune condition in which the body's immune system is predisposed to recognize normal things in your body as foreign invaders that need to be attacked.
The results are not specific for any particular disease if positive, but are a preliminary test, after which a range of possibilities are considered.

In brief: Autoimmune screen

A blood test. A positive ANA test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction.
This may indicate lupus, rheumatoid arthritis or scleroderma. Some people have positive ANA tests even when they're healthy, so further confirmatory tests are needed.
