In a period of six months I was diagnosed ANA positive 1:80 twice(FANA menthode), and anti-RNP bordering, once 1,0 and the second time 1.1 (border line is 1.0). I was tested U1-RNP which was negative both times. All the other exams are also negative. Doctors say I don't have any autoimmune disease, because of all the negative results, these two bordering ones and no phisical manifestations , but I don't know what to think? Is it possible that this tells a future eventual autoimmune disease?
Most Rheumatologists, if not virtually all, do not consider that titre negative. It can be raised to that level by a passing virus, age or merely having a relative with an autoimmune disease. Of course, I am just a patient, and only a Dr can make diagnoses. But were I you, in light of no symptoms, I would not worry one bit.
if you look up a blood test result site....they tell you that people with as high as 1:360 can still be without disease. mine was up and down for 3 years but has stayed up and gotten higher in the last two and with additional testing, i was definitely diagnosed with sjogrens. so the previous poster was right. if you're not symptomatic....don't worry about it.
