As I mentioned before, it is possible to have negative tests and still have the disease (or some form of an auto-immune disease). A negative ANA does not preclude one from having Lupus. The SSA ( also called anti-Ro) test is an autoantibody test that can be associated with systemic lupus (SLE) or Sjogren's Disease. Having a negative SSA also does not preclude one from having Lupus.
The ANA test is ordered to help screen for autoimmune disorders and is most often used as one of many tests to help diagnose Lupus. Doctors must also take into account your symptoms and, depending on the symptoms you display, ANA may be ordered along with one or more other auto-antibody tests. These tests includes tests to determine if inflammation is present, such as: erythrocyte sedimentation rate (ESR) and/or the C-reactive Protein (CRP) test. Please remember that the ANA may must be used, in conjunction with other tests and symptoms, before a diagnosis is confirmed or rejected.
So, if ANA (and other tests) are negative, but you still display symptoms, Doctor's are supposed to do further testing to find out what is (and is not) going on!!
I wish you the very best...do not give up, we are here to help you as much as we can.
