Special instructions for collection
Useful: in patients with rash and suspected Sarcoptes scabei infection.
Unroof the burrow hole. Using a scalpel or needle with immersion or mineral oil on it (which mites adhere to), scrape the superficial layer of skin 6 or 7 times vigorously (stratum corneum). Place the scrapings in oil on a microscope slide, place a second slide on top of the specimen and tape together, and safely transport to the laboratory. Additionally small piece of tissue can be sent with a few drops of oil on it.

General additional information
Whilst the sensitivity of skin scrapings is low, it is very specific and a mite or eggs seen under the microscope will remove any diagnostic doubt.
