Mucus in Urine

What is a mucus in urine test?

Mucus is a thick, slippery fluid that coats and moistens certain parts of the body, including the nose, mouth, throat, and urinary tract. A small amount of mucus in your urine (pee) is normal. Too much mucus may be a sign of a urinary tract infection (UTI) or other medical condition. A urinalysis test checks a sample of your urine. It can find out if there is too much mucus in your urine.

Other names: microscopic urine analysis, microscopic examination of urine, urine test, urine analysis, UA

What is it used for?

A mucus in urine test may be part of a urinalysis. You may have a urinalysis during a routine checkup to check your general health or to monitor a medical condition. Your health care provider may also order the test if you have signs of a urinary tract infection (UTI) or other condition that can cause mucus in your urine.

A urinalysis may include a visual check of your urine sample, tests for certain chemicals, and an examination under a microscope to look for certain types of cells. A mucus in urine test is part of a microscopic exam of urine.

Why do I need a mucus in urine test?

A urinalysis is often part of a routine checkup. Your provider may include a mucus in urine test in your urinalysis if you have symptoms of a UTI. These may include:

• Frequent urge to urinate, even when you have little urine in your bladder
• Pain or burning while urinating
• Dark, cloudy, or reddish-colored urine
• Bad smelling urine
• Pain or discomfort in your lower abdomen (belly)
• Weakness
• Fatigue

What happens during a mucus in urine test?

You will need to give a urine sample for the test. A health care professional may give you a cleansing wipe, a small container, and instructions for how to use the "clean catch" method to collect your urine sample. It's important to follow these instructions so that germs from your skin don't get into the sample:

1. Wash your hands with soap and water and dry them.
2. Open the container without touching the inside.
3. Clean your genital area with the cleansing wipe:
   • For a penis, wipe the entire head (end) of the penis. If you have a foreskin, pull it back first.
   • For a vagina, separate the labia (the folds of skin around the vagina) and wipe the inner sides from front to back.
4. Urinate into the toilet for a few seconds and then stop the flow. Start urinating again, this time into the container. Don't let the container touch your body.
5. Collect at least an ounce or two of urine into the container. The container should have markings to show how much urine is needed.
6. Finish urinating into the toilet.
7. Put the cap on the container and return it as instructed.

If you have hemorrhoids that bleed or are having your menstrual period, tell your provider before your test.

Will I need to do anything to prepare for the test?

You don't need any special preparations for this test. If your provider has ordered other urine or blood tests, you may need to fast (not eat or drink) for several hours before the test. Your provider will let you know if there are any special instructions to follow.

Are there any risks to the test?

There is no known risk to having a urinalysis or a test for mucus in urine.

What do the results mean?

A normal test result usually shows a small or moderate amount of mucus in your urine.

A large amount of mucus may be a sign of a medical condition, including:

• A urinary tract infection (UTI)
• A sexually transmitted infection (STI)
• Kidney stones
• Irritable bowel syndrome (IBS)
• Bladder cancer

If your test shows a large amount of mucus in your urine, you may need more tests to find out why. To learn what your results mean, talk with your provider.

Is there anything else I need to know about a mucus in urine test?

If a urinalysis is part of your regular checkup, your urine will be tested for various substances along with mucus. These include red and white blood cells, proteins, acid and glucose levels, and the concentration of particles in your urine.

If you get frequent UTIs, your provider may recommend more testing and steps to help prevent future infections.
