My first ANA was 1:320. 10 mos. later it doubled to 1:640, and then 6 mos. later to 1:1280. I think the last one was 1:640 in Nov.(when I was actually feeling worse than ever). Started Plaquenil in Dec. Am curious if it will have gone down further, however, I believe the ANA's fluctuate enough that they don't necessarily reflect disease activity. I have a friend who's had Lupus for years and she said her rheumy never checks the ANA anymore - says that once it's significantly positive, there's no need to. I don't know how correct that is....my rheumy seems to repeat all that bloodwork on a regular basis. Waiting for something else to "land" I 'spect.
The patterns have been, respectively, Nucleolar and Homogenous initially, then just Homogenous, then Nucleolar and Speckled. My rheumy doesn't find that to be especially helpful diagnostically. I have a follow-up appt towards the end of this month - will see what, if anything has changed.
I'm not sure what your second number (243) reflects?
