    Default ANA question

    Hi

    I have been trying to find a range of what a "normal" person's ANA should be, and I can't find what I am looking for.

    My ANA was 1:320 last time it was checked in July. I am mostly wondering if that's high? Also, how often do they usually test your ANA?

    Just curious.

    Thanks!

    Hiya,

    I had a look about and it seems that no sites agree! A couple said that anything less than 1:320 was negative, but they also said that a negative value rules out SLE, which isn't true since 5% of SLE patients have negative ANA's.

    I also read that values vary according to sex, weight, ethnicity and a few other things.

    May be a question for your rhumy to see what he views as normal!

    Hi ya, SoleSinger! Well, for Canada, at the lab my daughter goes to,
    <35 kU/L is negative
    35-55 kU/L is equivocal
    >55 kU/L is positive.
    I know this probably doesn't help, because it is metric. I always get a copy of all lab reports, doctor and hosiptal reports. Try asking your Rheumy or GP for the reports. Purhaps, like ours, you will have the normal ranges on all lab work on the report. I have a large binder seperated into different categories for my daughter's health binder. I have a personal information section, important phone numbers(dr.'s and family members) section, lab results, Physical therapy, Nutrition section, Medication section , information about SLE, arthritis, myositis, and a section to jot down questions and correspondance. I hope that this helps someone.

    EVERYTHING GOOD IS POSSIBLE !!!

    Hi SoleSinger,

    According to a copy of one of my reports, it lists the reference range as:

    <1:40 Negative
    1:40 - 1:80 Low Antibody Level
    >1:80 Elevated Antibody Level

    So, I guess 1:320 would be a bit high, but mine has gone as high as
    1:1280. http://www.uklupus.co.uk/ana.html is a pretty good site I found w/ a good description of the ANA test. Hope it helps!

    Mitch
