Lupus Support Group
Lupus is an auto-immune disease in which the immune system cannot distinguish between threats (like viruses and bacteria), and healthy cells and tissue. As a result, the body produces antibodies that inflict cell damage, most commonly targeting joints, skin, kidneys and the nervous system. Join the group and find support for coping with lupus.
The ANA test isn't perfect though, about 5% of people with Lupus have a negative ANA. And titer can vary a lot. I've read of people having a negative ANA one month and next month 1:320. A lot of doctors will say you don't have Lupus/Connective Tissue Disease if your ANA is not elevated, but then if you do have an elevated ANA they're not interested unless it's over 1:640.
The pattern Homogenous is most commonly found in Lupus and Mixed Connective Tissue Disease. There's not H next to your anti-dsDNA, so I would assume that wasn't elevated. However there are other antibodies found in Lupus such as anti-SM, anti-ssDNA, anti-histones and anti-RNP which is found in MCTD.
Some people with RA do have a positive ANA, so that may explain it. Also if you have 'dry eye syndrome' you could have Sjogren's. Have you had anti-SSA and anti-SSB tested? Sjogren's is common as secondary to RA.
Just be prepared for them to dismiss your ANA result entirely, because I've heard it/had it happen.
Good luck.
