What is it?
Discolouration, thickening, brittleness and lifting of the nails may be due to fungal infection, but also to psoriasis, trauma or other causes. Identifying the cause before treatment is therefore important.
The assessment includes nail examination, dermoscopy and, if needed, a fungal test on a nail sample. If fungal infection is confirmed, topical or oral treatments are considered depending on the extent.
Because nails grow slowly, treatment can take a long time and response varies between people. The treatment and its duration are decided with your doctor after examination and test results.
Who is it assessed for?
- People with yellow-brown nail discolouration

Questions
Is every nail change fungal?
No. Other causes such as psoriasis and trauma can look similar.
Can I wear nail polish before sampling?
If a sample will be taken, removing polish and nail products beforehand and avoiding them for a while is advised.

Fungal infections can spread through shared towels, slippers and wet floors; keeping personal items separate is advised.
