question: Hello. I have systemic lupus (calm). I usually get lab work done 1-2 times a yr. to check my kidney, etc. due to the lupus.  Three yrs. ago, June 2010 Ive been having occult blood (1) in my urine. I asked my Rheumatalogist and she said I probably took the urine test close to my period or near the end of my period and thats why it showed the occult blood, so I didnt worry anymore. This July I had my lab work done and again the occult blood (1) showed up (as it has been in the last 3 yrs.). This time however my Rheumatologist was concerned and told me to see a urologist. Because I couldnt see a urologist sooner, I went to see my family doctor. He ordered a urine test and an ultra sound of the kidney. He diagnosed me as microhematuria. When I finally saw the urologist, she ordered a urine cytology and recd that I get a cystoscopy esp. because my lab showed  occult blood (1) along with rbc 4-10 . She wanted to make sure that I dont have a bladder cancer or kidney disease so a cystoscopy needed to be done. When I did the urine test that day, I believe the cup was contaminated thats why it showed the rbc 4-10. When repeated, it didnt show rbc 4-10, but normal  rbc 0-2 (below)Results
