i am one of the members with kidney nephritis, my docs were able to diagnose me very quickly because i had alot of the phsyical syptoms of lupus, plus i was spilling protein and blood in my urine, and my creatinine was extremely high. have you done a 24-hr urine or regular blood work that included a CMP? and rosie is right, the best way to detect lupus especially in the kidneys are with a biopsy because not only does it tell you if your kidneys are being attacked but also how badly they are being attacked and how much damage the lupus has done. i also have medical background and i know that some kidney issues are not always a result of lupus. so i would say do jump to conclusions but see the docs and get answers. good luck.
