Generally Lupus is diagnosed by what they call "4 of 11" - meaning you have at least 4 of the 11 listed symptoms, only one of which is an ANA test. You can read more at 'diagnosing lupus' in my signature below.
Dunno what Drs you have been seeing, but a rheumotologist is the Dr who is the expert on Lupus and the only one who I'd truely truth for diagnosis. Even then, there are Drs who won't diagnosis without a positive ANA and others who are more symptom oriented.
Are you being given any treatments? One way the rhuemies work on getting a diagnosis is to see what medications your symptoms respond to.
Hope that helps, best wishes -
