I have seen a nephrologist, and he was very kind and compassionate. My kidneys are testing borderline functional, i do have blood in my urine, and have for many years. My dr. said lupus nehpritis always has protein in urine, and i don't show any protein, so we are not sure what is going on with me. However, he said there is no emergency, he is going to watch closely for a while. I do know that diagnosis of lupus nephritis involves a 24 hour urine collection, and I think a kidney biopsy. If diagnosed with lupus nephritis, they can treat, so that is good news. Also, we can live on 1 kidney, so if one goes out, we can still function.
good luck....will keep my fingers crossed for you wednesday.
