A member asked:

Feel great - incidental finding ana 1:160 after acute sinusitis. then had anti-dna, ant-smith, ssa/ssb, rnp, scl-70, centromere, and thyroid labs all normal. does this exclude autoimmune disorder?

Relax, man: Around one person in four has a lowish titer of ANA like yourself. Feeling well is the best indicator that you're not sick. I'm sorry that you had to have the other labs run -- but at least you can be thankful you're not a lupus patient. If the sinus problem doesn't go away, the correct action is to test for Wegener's with an ANCA.

1:160: Almost certainly yes but keep an eye on it. If you notice any change please see your doctor.

No: You need to provide more specific information. Why were these tests ordered in the first place? A positive ANA alone needs to be evaluated in the context of the clinical symptoms in order to determine in it has significance.

False positive ANA: ANA positivity very common in general population. You had the correct assessment showing no common autoimmune diseases. A repeat ANA can be 1:80 as you rid infection. It is a non specific test till titers of 1:640.
