Identifying a nail fungus involves looking for specific signs that indicate an infection. One of the most common indicators is observing discoloration, which may appear as yellow, brown, or even green spots under the nail. In addition to discoloration, thickening of the nail is often present, where the nail plate may become more pronounced due to an accumulation of keratin and debris. Another telltale sign is the separation of the nail from the nail bed, which can occur as the infection progresses. These visual symptoms are characteristic of fungal infections and help professionals diagnose the condition accurately.

Nail polish residue may mask the underlying problems but does not help identify fungal infections. Unusual odors could suggest an issue but are not definitive signs of a fungal infection on their own. Finally, while examining nail shape and length can provide information about overall nail health, they are not specific indicators of a fungal infection. Thus, observing the visual signs of discoloration, thickening, and separation is critical in identifying nail fungus.
