Hi my urine test result: Protein: Trace, ketone: 2+, Occult Blood, Urine: 1+, Rbc: 20, my doctor said I might have a kidney problem and he wants me to do x-ray and ultra sound for my kidney to check if I have kidney stone. I 've been sick for a while and my right back is painful, but i do not think I have kidney stone because I heard the pain is extreme and mine is only mild. Should I still do ultra sound and x-tray ? or Is there any test to find out what's wrong w me ?
