Does a negative ANA mean I can rule out all autoimmune, or only some?
It means you can't really rule out anything unfortunately.
It's very general and it's totally possible to have autoimmune diseases and be ANA negative. It's more rare but it definitely happens, especially if you have low levels of antibodies in general.
