Thanks Kiwi- I only have as much information as I've posted here about my ANA - no breakdown yet.

I'm assuming that it is very significant in my case, given that I've been told by my previous rheumatologists that I can't have a connective tissue disease without it - despite raised inflammatory markers, paired o bands and many symptoms corresponding with connective tissue diseases. Also I have never understood how it is possible that we allow RA to be clinically diagnosed and treated in seronegative form - but not the others? I suspect this is because synovitis and RA erosion show up clearly in imaging so can't be refuted - unlike diseases such as Lupus or Sjogrens which can be much harder to confirm without the autoantibodies.
