Blood in your urine is called hematuria. The amount of blood may vary. It may be very small and only detectable during a urine test. In some cases, the blood may be visible in toilet water following urination.


Blood in urine is a symptom of numerous disorders. These disorders range from benign to very serious. Therefore, it is important to have a physician determine the cause of your bloody urine and a course of treatment.

Call your doctor immediately if you also:

  • Have fever, nausea, vomiting, shaking chills, or pain in your abdomen, side, or back
  • Are unable to urinate
  • Pass blood clots in your urine


Your physician will perform a physical exam and ask you questions about your condition. Testing may include:

  • Blood tests
  • Urinalysis
  • Imaging such as ultrasound or CT

Findings from these and other tests may indicate the need for additional testing.
