Urine culture

This test identifies bacteria in urine. It is used to diagnose and manage urinary tract infections.

Laboratory tests may be done for many reasons. Tests are performed for routine health screenings or if a disease or toxicity is suspected. Lab tests may be used to determine if a medical condition is improving or worsening. Lab tests may also be used to measure the success or failure of a medication or treatment plan. Lab tests may be ordered for professional or legal reasons. You may need this test if you have:

• Asymptomatic bacteriuria in pregnancy
• Inflammation of epididymis
• Nongonococcal urethritis
• Prostate inflammation
• UTI - Urinary tract infection

To prepare for giving a urine sample, be sure to drink enough fluids before the test, unless you have been given other instructions. Try not to empty your bladder before the test.

Immediately before a test that requires a clean urine sample, males must clean, rinse, and dry the head of the penis. Females must clean, rinse, and dry the urethral area. As you begin urinating, allow a small amount of urine to go into the toilet, and then stop the urine stream. Position the container to collect your urine, and urinate into the container. Remove the container when it has a sufficient amount of urine in it, and finish urinating into the toilet.

The urine sample may also be collected from a urinary catheter. If a catheter is present, the healthcare worker will collect urine from the catheter for testing. If there is no catheter present, a catheter may need to be inserted temporarily to collect the sample. The area will be cleaned, and a sterile catheter will be inserted into your urethra. Urine will drain from the catheter into a container for the test. When sufficient urine has been collected, the catheter will be removed. A special bag may be used to collect a urine sample from an infant.

The amount of discomfort you feel will depend on many factors, including your sensitivity to pain. Communicate how you are feeling with the person doing the test. Inform the person doing the test if you feel that you cannot continue with the test.

There is usually no pain experienced when a clean-catch urine sample is given or when the sample is taken from an existing urinary catheter. If an intermittent (temporary) catheter is used to obtain the sample, you may feel some discomfort.

After collecting a urine sample, close the container if it has a lid. Place the container where the healthcare worker asked you to put it. Clean your hands with soap and water.

You have the right to help plan your care. To help with this plan, you must learn about your health condition and how it may be treated. You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
