Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like unusual discharge, itching, burning during urination, or frequent urination. It can also be used to monitor people with weakened immune systems or those taking long-term antibiotics, which can increase yeast risk.

What to Expect Before the Test

No special preparation is needed. You’ll provide a urine sample in a clean container. Avoid using vaginal creams, douches, or spermicides for 24 hours before testing to ensure accurate results.

What the Test Involves

A small amount of your urine is collected and placed on a special growth medium. Lab technicians then observe for yeast growth over 24–48 hours. If *Candida albicans* is present, it will appear as fuzzy, white colonies.

What the Results Mean

A positive result means yeast was found in your urine. This doesn’t always mean you have an infection—some people carry yeast without symptoms. A negative result means no yeast was detected, but other causes of symptoms (like bacteria) could still be present.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result suggests a possible urinary yeast infection caused by *Candida albicans*. However, further testing (like a urine microscopy or culture for bacteria) may be needed to rule out other infections. Your provider will guide next steps, such as treatment if needed.
Can I get false results?
Yes, false positives or negatives can happen. For example, yeast may be present in urine without causing symptoms (called *asymptomatic carriage*). False negatives can occur if the sample isn’t handled properly. Your provider will interpret results in context with your symptoms and medical history.
How often should I get this test?
This test isn’t routinely recommended for healthy individuals without symptoms. It’s typically ordered when you have signs of infection, like recurrent urinary tract issues or a history of yeast infections. Follow your provider’s advice for follow-up testing if needed.
