Have lupus.on plaquenil.recent labs cbc, c3, c4, bmp, &ua showed no concerns. no other tests done. does that mean my intermittent flares of debilitating fatigue & near syncope is not be from lupus? rheumatologist never addressed & said labs look good?

Did you have COVID-19? Review with Dr. May be able to get COVID-19 antibody test to see unless you COVID shots. If you have not gotten them please do.

Those tests aren't sufficient to explain your intermittent severe fatigue and near syncopal.episodes. I should think that a rheumatologist, who also is trained in general internal medicine would do a more complete workup other than evaluate your lupus status. Thyroid testing, vit B12 level,iron & iron binding capacity,, EKG,echocardiogram and possible neurological referral should also be done
