I've had a few connective tissue/autoimmune symptoms for the past 6 months.
My ANA has been positive at 1:80 for the past 3 tests (over 3 years). CRP and Rheumatoid Factor all normal.
It's been suggested I might have undifferentiated connective tissue disease (http://emedicine.medscape.com/article/334482-overview).
The diagnostic criteria states-
"....In order to fulfill the criteria for UCTD, antinuclear antibodies must be present, along with a disease duration of at least 3 years"
At 1:80 is this considered 'present'?
