Diagnosis of Athlete’s Foot
The diagnosis of athlete’s foot is usually straightforward. Doctors can often recognise it through physical examination alone, based on the visible signs: scaling skin, cracking between toes, itching, or burning.
If needed, further tests may be done:
- Skin scraping: A sample of skin is examined under a microscope.
- KOH test: A potassium hydroxide solution helps detect fungal elements.
- Fungal culture: Used for persistent or unclear cases.
In South Africa, many mild cases are treated over the counter, but chronic or recurrent infections should be seen by a GP or dermatologist. Early diagnosis prevents the infection from spreading to the toenails or other areas like the groin or hands.
