Re: Positive ANA AB Titer with Nucleolar Patter??
I can only speak to the sclero side of UCTD, but my understanding is that complement does not drop in sclero, usually but not always. In fact, mine is usually high. I believe that complement levels in lupus are lower than in MCTD. I also think that lupus specific and sclero specific antibodies are absent in MCTD. I don't know about the ANA patterns, but the specific antibodies, like anti-DSDNA and anticentromere and the like. UCTD also can have low complement levels.
