Help docs! i'm trying to find out what causes blood and white cells in urine?

Blood in urine: Blood is not normally in urine. If there is blood (rbcs and wbcs) in the urine and nothing else abnormal, then blood is entering your urine in some way. Are there symptoms like burning with urine, flank pain, recent infection, etc? In females this is common with recent period. See your doctor for further follow up as this needs to be looked at in a clinical context to be sure everything is good.
