May of us have been fully diagnosed without a positive ANA. Lupus is not easily diagnosed, as there are NO tests that say definitely "this is lupus". Instead there is the "4 of 11" rule, where 4 symptoms (and a qualified rhemuy) are enough for a diagnosis.
And, many of us have been successfully treated without a diagnosis! Reducing the symptoms is often more important than getting them named.
