I didn't find much about
anti-dsDNA titers either. The one reference to titer I found just said positive is >1:10 which would mean you are right, it's "low". It looks like it's a predictor of symptoms, that is, if the titer is going up, your symptoms can be expected to increase.
Of course, we know titers have different ranges depending on how a specific lab does the test, so if you can get the actual lab report maybe it will specify what it thinks is low, medium, high.
By searching Healing Well, I did find this comment from a member in 2008, "Over the last year my Anti dsDNA has continued to rise. First blood test the showed 1500 (normal being 0 to 99). Blood test last week was 2,697."
That doesn't really help if yours is reported in titers, but maybe you can search HW and find more info?
Sorry I'm not more help, maybe someone else has more information.
