The ANA number is not an indicator of disease activity.
The only blood test that fluctuates in relation to flares and how you are feeling are the inflammation markers
... and they don't diagnose Lupus since there are probably hundreds, if not thousands, of things that cause inflammation.
You can have flares with AND without a positive ANA. You can have a positive ANA with AND without Lupus.
The ANA is only one symptom, out of 4 needed for a Lupus diagnosis. If you have paperwork from a rheumy diagnosing you with Lupus, that should give e new Dr a starting point, but it isn't "starting over" because old Dr or new Dr, they still have to treat you based on what is going on with you at the present time.
