Lupus is not really diagnosed by bloodwork - it is more difficult than that to pin down and is diagnosed by symptoms. Typically, four or more of the following eleven criteria must be present to make a diagnosis of Systemic Lupus.
1. Malar rash: butterfly-shaped rash across cheeks and nose
2. Discoid (skin) rash: raised red patches
3. Photosensitivity: skin rash as result of unusual reaction to sunlight
4. Mouth or nose ulcers: usually painless
5. Arthritis (non-erosive) in two or more joints, along with tenderness, swelling, or effusion. With non-erosive arthritis, the bones around joints don’t get destroyed.
6. Cardio-pulmonary involvement: inflammation of the lining around the heart (pericarditis) and/or lungs (pleuritis)
7. Neurological disorder: seizures and/or psychosis
8. Renal (kidney) disorder: excessive protein in the urine, or cellular casts in the urine
9. Hematologic (blood) disorder: hemolytic anemia, low white blood cell count, or low platelet count
10. Immunologic disorder: antibodies to double stranded DNA, antibodies to Sm, or antibodies to cardiolipin
11. Antinuclear antibodies (ANA): a positive test in the absence of drugs known to induce it.
ANA is only one of the criteria - you can have Lupus both with and without a positive ANA. Have you ever seen a rheumotolgist? That is the only Dr who I would trust to make a definitive Lupus diagnosis.
Best wishes.
