I'm hoping I can help put your mind at ease some. I had a positive ANA titer of 1:1280 Homogenous pattern. I was very worried also...
The pattern is what gives the rheumatologist an idea as to what kind of autoimmune disease to test for and helps them to know what additional blood work to run. If its any consolation at all my ENA screening panel (blood work) that the rheumatologist ran on me, came back negative for everything, lupus, rheumatoid arthritis, scleroderma, and other connective tissue disease. Now they just test me every six months to make sure nothing changes. I also have joint pain, muscle pain, headaches etc. I wonder if the coeliac disease you mentioned you have could be the reason for your positive ANA? Its something worth asking your rheumatologist about
. Please keep us posted. Best wishes
