Other descriptions are sometimes used such as: a trace of blood in urine, red blood cells (RBCs) in urine, or visible blood in urine. When blood in urine is microscopic, the severity is measured as red blood cells (RBC) per high power field (HPF) under the microscope. Usually, >3-5 RBCs/HPF is considered abnormal. With >20-50 RBCs/HPF, a significant urological or medical problem often exists. Blood in urine can originate from the kidneys, ureters, urinary bladder and the urethra.
