What your results can mean
Reading your report

If the result is outside the usual range
Growth can identify the fungus or yeast causing an infection of the nails, skin, lungs or urine. Some yeasts live normally on the body, so growth is read with symptoms.
Who usually has this test
People with fungal nail or skin infections that are not improving, and people with weak immunity and a suspected fungal infection.
Risks and aftercare
Scraped skin or nails may feel slightly sore for a short while.

Questions about this test
Can antifungal treatment affect the result?
Yes, recent antifungal creams or tablets can stop fungi growing in the lab. Tell your doctor, who will advise on timing before the sample.
How is a fungal culture different from a KOH mount?
A KOH mount quickly shows whether fungi are present. A culture grows them so the exact type can be identified.
Why does a fungal culture take longer than a bacterial culture?
Many fungi grow slowly, so cultures are kept for longer before being called negative. Ask the hospital when to expect your result.
