Blood in Urine: Causes, Diagnosis and Treatment

When there is abnormal blood in urine, it can be a sign of an underlying health condition that requires medical attention. Blood in urine, sometimes referred to as hematuria, could be symptomatic of an underlying infection, kidney disease, bladder cancer, or other serious medical conditions.

Preparation for Blood in Urine Tests

In order to diagnose the cause of blood in urine, a doctor may ask you for pre-test preparation, such as providing a urine sample. Some tests may require the patient to collect urine for a period of time or discontinue certain medications temporarily. Other tests may require that you fast before coming for your appointment.

Types of Blood in Urine Tests

Depending on the situation, doctors may order certain tests to identify the causes of the condition:

  • Urine cultures: Look for bacteria and organisms that may be causing infection
  • Complete blood count (CBC): to identify any changes in red and white blood cells
  • Kidney and bladder ultrasound: to view the size, shape, and structure of the kidneys and bladder
  • Biopsy: to remove a sample of tissue for examination
  • Urine microscopy: to analyze the sample for presence of red and white blood cells
  • Urine cytology: to identify any changes in the cells present in the urine
  • CT scan: to look for any structural abnormality in the urinary tract
  • Intravenous pyelogram (IVP): to look for blockages or narrowing of the urinary tract

Risks of Blood in Urine

The most common risks associated with blood in urine are infection, kidney disease, bladder cancer and other serious medical conditions. If the condition is left untreated, it could lead to further complications and may even cause death. It is important to seek medical attention as soon as possible.

When to See a Doctor

It is important to discuss any changes in your urine with your doctor, especially if it is accompanied by other symptoms such as pain, fever, fatigue, or frequent urination. It is also important to get tested if you have a history of kidney or bladder disease, or if you are pregnant.


Blood in urine can be indicative of an underlying medical condition and should not be ignored. It is important to discuss any changes in your urine, or other symptoms such as pain, fever, or frequent urination with your doctor. Be sure to discuss your medical history and any medications you take to determine the best course of action.
