Urine Culture

Overview & Description | Preparation & Expectations | Results and Values

A urine culture is a test done on a sample of urine. The urine is smeared on a special culture media in the lab and allowed to grow. It is then examined to see if there are infection-causing organisms present. If there are, the organisms are identified under a microscope.

Who is a candidate for the test?

A urine culture is ordered to see if a urinary tract infection is present.

How is the test performed?

There are two methods for collecting urine: the clean-catch method and the catheterization method.

Clean-catch method

In this method, the person is given special disposable wipes and a sterile container to hold urine.

  • First, the person uses the wipes to clean around the urethra, the tube that passes urine out of the body.
  • Next, the person urinates a small amount into the toilet and stops before the bladder is empty.
  • The person collects a urine sample in the container provided.
  • Finally, the individual finishes by urinating into the toilet.
  • Catheterization method

    This method can be used when the person has difficulty urinating or is unable to cooperate.

  • First, the area around the urethra is washed to prevent contamination.
  • Next, the healthcare provider passes a sterile, lubricated catheter through the urethra and into the bladder.
  • Urine flows through the tube into the sterile container. The provider removes the catheter when the sample has been collected.
  • In the lab, the urine sample is grown on culture media. If any disease-causing microorganisms grow on the culture plate, these are identified. A sensitivity test may also be done to identify antibiotics that will kill the organisms. This allows the provider to choose a treatment program.
