Did they say what 'pattern' of ANA?
If you have one autoimmune disease, you often get another. Other things can push ANA up, including infections, medications, chemical or other exposure, etc.... It doesn't have to be a serious illness or autoimmune disease... My ANA has been all over the place- from normal to high- for the past 10 years. Yes, there is a connection to IF and fsh, but not many are up to date on the research.
