I have read that the birth control pill can affect your ANA. Does anyone here know how? I'm interested in this because only a few things changed between my positive ANA and my negative ANA. One was that I was put on the Nuvaring to control menstrual bleeding, and iron for anemia. Steroids can cause a false negative, and steroids are hormones too.

Also, can Plaquenil affect your ANA? I've been on that for a little over 2 years now. I have read that it's to help alleviate and stop the progression of symptoms. Nothing about if it affects ANA.

Thanks and smiles,
