Fungal Culture Test Test
A fungal culture test checks for fungi (like yeast or mold) in a sample from your body. It helps find out if a fungus is causing an infection and what type it is.
What this test measures
A fungal culture test helps diagnose fungal infections by growing any fungi from a sample (such as skin cells, blood, or urine) in a lab dish and then checking it under a microscope.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Higher-than-normal results
A positive test result means a fungus was found in your sample. You most likely have a fungal infection. Your test results will usually identify the specific type of fungus causing the infection.
Lower-than-normal results
A negative test result means that no fungi were found in your sample. Something else is probably causing your infection.
