    Default I have a question about ANA but was not sure where to post this!

    I have a question. I am new to this site and am still trying to figure out how everything works. I was diagnosed with Lupus about 3 months ago. My doctor told me that my ANA went up 3 times what it was 6 months ago and she said it is now a 12. and that .9 was normal. I have researched and looked for information regarding the ANA and am totally confused now. I read something about a titer or something and none of this is making any sense to me. Can someone please try to explain this in a ANA for dumbies type of way?

    I am not sure this is where I should have put this. If not I am sorry for that. Still trying to figure this website out please bare with me I am hoping I will eventually get it.

    I think due to the fact that I have been told so many times I am nuts and not in pain and there is nothing wrong with me that I am a little leary of anything I do right now.

    Thank you for being patient with me.

    ANA AND TITERS(along with its pattern) is one of the many tests done when looking for lupus or other autoimmune diseases. Since there is no actual test for Lupus it is just a guide. When the ANA gets high it doesn't mean you have Lupus but it usually makes the doctor start doing more tests to see what is going on

    The lab your dr is using may be using an ANA test that does not report the number in a titer fashion.

    There is an ANA that reports the value in a number-which seems to be the one you had done.

    The titer is one where they take the blood and dilute it until there is no autoimmunity noted.The titer you end up with is the last dilution that they had to perform until there was no abnormality noted in your blood sample-each dilution doubles the titer number resulting in the diagnostic read.

    So one dilution(and then if no abnormality noted)would be a titer of 1:40 as a result
    two dilutions would be 1:80(if they detected abnormality at 2nd dilution but none at the 3rd)
    three dilutions would be 1:160(if they detected abnormality at 3rd dilution but none at the 4th and so on)
    four dilutions would 1:320
    5 would be 1:640

    Hope this helps some and take care.
