- For nail samples, avoid nail polish for several days prior.
- Inform your dermatologist about any medications or supplements you are taking.

Risks & possible complications
- The procedure is extremely low-risk. The primary 'risk' is a false-negative result if the sample is inadequate or if antifungal creams were recently used.
- Minor, temporary discomfort during sample collection (gentle scraping).
- Very slight risk of minor bleeding or irritation at the sample site, especially if the skin is already inflamed.
- No risks associated with the KOH solution itself, as it is used externally for examination only.
Recovery & hospital stay
- No recovery time is needed; patients can resume normal activities immediately.
- The sampled area may feel slightly tender or look mildly irritated for a few hours.
- Keep the area clean and dry; follow your dermatologist's instructions regarding any ongoing skin care.
- If a biopsy or more invasive sample was not taken, no wound care is required.
- Await the results, which are often discussed during the same appointment, to begin the prescribed treatment plan.
