What is skin scraping? A skin scraping is a basic dermatological procedure. It is performed using a blade, a glass slide, and mineral oil. The skin is scraped either superficially or deep to search for mites (parasites) that live on the skin surface or hair follicle, respectively. This procedure is not intended to cut the skin, but rather scrape the skin.
Why do we have to perform skin scrapings at the outset of a dermatological diagnostic work-up? Skin scrapings are necessary for the majority of dermatological diagnostic work-ups. Diseases such as demodectic mange can usually easily be diagnosed by this method. A small amount of liquid paraffin is placed onto the skin and the skin is then gently scraped until there is oozing of blood from capillaries. Scrapings have to be this deep as these demodex mites live deep down inside the hair follicles.
