Fungal Culture from Urine

Why Is This Test Done?

Your healthcare provider may order this test if you have symptoms like persistent urinary symptoms (e.g., burning, frequent urination), unexplained fever, or signs of a systemic fungal infection. It’s also used to confirm a fungal infection in the urinary tract, especially in patients with weakened immune systems or risk factors like diabetes or catheter use.

What Does the Test Involve?

A urine sample is collected (often via midstream clean-catch or catheter) and sent to a lab. The sample is then cultured to grow and identify any fungal organisms that may be present. Results take several days to weeks as fungi grow in the lab.

How Is the Test Performed?

The urine sample is placed on a special growth medium in the lab. Fungi, if present, will grow into visible colonies over time. The lab then identifies the type of fungus based on its appearance and characteristics.

What Are Common Findings?

Positive results indicate the presence of fungi in your urine, which may require treatment with antifungal medications. Negative results mean no fungi were detected in the sample, but other causes of symptoms should still be evaluated.
