I have been battling with having kidney stones over the last few months. My most recent urine test showed occult blood 3+. I know that is most likely a direct result of the kidney stone. (Although my most recent CT scan didn't show a stone. The doctor said that it may be to small to pick up) But the part that caught me off guard was the PROTEIN 2+ (normal levels are negative) and BILIRUBIN 1+ (normal levels are negative) This is my 3rd ua within the last 2 weeks and this is the only test that has showed the protein and bilirubin. Should I be alarmed?
