Why Is This Test Done?

Your healthcare provider may recommend this test if you have symptoms like itching, redness, swelling, or unusual discharge in the genital area, or if you’ve been diagnosed with a fungal skin condition. It’s also used to confirm infections in people with weakened immune systems or recurring fungal issues.

What Does the Test Involve?

A healthcare professional will collect a sample from the preputial folds, barnacles, or sulcus using a sterile swab. The sample is then sent to a lab, where it’s grown in a controlled environment to identify any fungal growth over time.

What to Expect Before the Test

No special preparation is needed, but avoid washing the genital area with harsh soaps or lotions before the test. Wear loose-fitting clothing to make access easier.

What to Expect During the Test

The procedure is quick and usually painless. You may feel slight discomfort if the area is irritated, but it won’t cause lasting harm. The sample is collected gently with a swab.
