Tests that may be done include:
ANAtiter BUNand creatinine Complementlevels Urinalysis

The goal of treatment is to improve kidney function and to delay kidney failure.
Medicines may include corticosteroids or other medications that suppress the immune system, such as cyclophosphamide, mycophenolate mofetil, or azathioprine.
You may need dialysis to control symptoms of kidney failure, sometimes for only a while. A kidney transplant may be recommended. People with active lupus should not have a transplant because the condition can occur in the transplanted kidney.
How well you do depends on the specific form of lupus nephritis. You may have flare-ups, and then times when you do not have any symptoms.
Some people with this condition develop chronic kidney failure.
Although lupus nephritis may return in a transplanted kidney, it rarely leads to end-stage kidney disease.
Acute renal failure Chronic renal failure End-stage renal disease Nephrotic syndrome
