Collection

  • Wash and dry the affected hand or foot
  • Use clean scissors or nail clippers to cut a small piece of the nail from where it is most badly affected (e.g. thickened, brittle, discoloured)
  • Include the full thickness of the nail
  • Cut as far back from the nail tip as possible
  • If the infection is on the underside of the nail, gently scrape out some debris (crumbly material) using the tip of the scissors

Packaging

  • Place the nail clipping and/or scrapings inside a Dermapak
  • Seal the Dermapak and place inside its plastic bag
  • Do NOT store in the fridge (sample must be kept at room temperature)

Transport

  • Make sure the sample is labelled with your name, date of birth and the date of collection
  • Bring the sample to your GP (or send to the laboratory) as soon as possible
