Do you mean that these diseases have all been misdiagnosed and what you really have is lupus? I'm not a doctor that's for sure. Lupus causes a lot of different symptoms and can be hard to diagnose. There are 11 criteria for lupus one of which is a positive ANA test. If you don't have that you probably don't have lupus and you've probably been tested for that by now. Here's some more information on a lupus diagnosis.
