Published: August 9, 2026Updated: August 16, 2026

This test checks for the presence of fungi in your urine, which may indicate an infection such as candidiasis (a yeast infection). It involves growing urine samples in a lab to identify fungal organisms and examining them under a microscope.

What This Test Measures

The test involves collecting a urine sample and culturing it on a special medium to allow fungal growth. Microscopic examination then identifies fungal structures, such as yeast cells or mold filaments, if present. This process helps confirm whether fungi are responsible for symptoms like persistent urinary tract infections or unusual discharge.

Why It’s Done

Your healthcare provider may recommend this test if you have symptoms like persistent urinary tract infections, unusual discharge, or signs of a systemic fungal infection. It’s particularly useful for patients with recurrent infections, weakened immune systems, or those who have not responded to standard antibiotic treatments.

Sample Collection and Preparation

A clean-catch midstream urine sample is typically collected. The sample is then sent to the lab, where it is cultured and examined under a microscope to detect fungal organisms. This process can take several days to yield results.

When Results May Be Abnormal

Positive results indicate the presence of fungi in your urine, which may signal a fungal infection. Negative results mean no fungi were detected in the sample, but other causes of symptoms should still be evaluated.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Fungal infections in the urinary tract can be more challenging to treat than bacterial infections and may require antifungal medications. Early detection through this test allows for prompt treatment to prevent complications, such as kidney damage or spread of infection.
