A normal red blood cell count in a urine test is 4 red blood cells or less per high power field, according to MedlinePlus. This is expressed as 4 RBC/HPF. It is normal for results to vary slightly from lab to lab.
A higher-than-normal RBC may signal kidney or urinary tract issues, a specific injury to the kidney, bladder or kidney cancer, or prostrate problems for men, reports MedlinePlus. In some cases, a doctor asks the patient to collect clean urine samples over a 24-hour period at home. Most often, a simple test is done in a health provider's office.
