How do I find out if I have a fungal nail infection?
If you think you have a fungal infection in your fingernails or toenails, see your doctor. By looking carefully at your nails, your doctor might be able to tell if you have an infection.
To be sure of what kind of infection you have, your doctor might scrape a little bit of tissue from your nail and send it to a lab. The test can tell if you have a fungal infection or another kind of infection.
