Ana Chromosome

What does it mean that I have positive ana screen and I'm also supposed to have rhematoid arthritis, the rheumatoid factor came negative?

[Kevin Pho, MD]

The ANA level is a marker for various rheumatological diseases - such as lupus and rheumatoid arthritis.  By itself, the result isn't useful - it has to be correlated with your symptoms, physical exam, and other blood tests.  Note, there is a small proportion of the population that will have a positive ANA screen.

If you have other symptoms consistent with arthritis or lupus, further testing can be considered.  At this time, I would consider a referral to a rheumatologist for further interpretation of this test.

Followup with your personal physician is essential.
