In brief: What do you mean?

Your question is confusing.
The ANA is simply a blood test and is basically a screening test for lupus although it can be positive in numerous other diseases and in normal. Do you mean rheumatoid factor test or rheumatoid arthritis? One is a blood test and the other a systemic inflammatory arthritis that can cause joint pain, swelling and damage.
