What Is the Average Red Blood Cell Count in Urine?
A normal result for a red blood cell count in urine is about four red blood cells or less per high power field when the doctor uses a microscope to examine the sample, according to MedlinePlus. Depending on the laboratory, slight variations may occur in normal value ranges.
An elevated red blood cell count in urine typically results from kidney infections, injuries, tumors, stones or cancer. Urinary tract, prostate and bladder problems can cause the number of red blood cells in urine to rise, notes MedlinePlus. Sickle cell anemia and medications such as penicillin, aspirin and cyclophosphamide, a cancer-fighting drug, can produce hematuria, or blood in the urine, explains Mayo Clinic.
