Collection Instructions Place insect in gauze or tissue moistened with water and submit in a clean container. Refrigerate until submitted to laboratory.

Skin scrapings for scabies: Scrapings are best performed at the end of the burrows in non-excoriated and non-inflamed areas using a sterile scalpel blade containing a drop of mineral oil. The mineral oil enhances the adherence of the mites to the blade and can then be transferred to a glass slide. Glass slides can be "sandwiched" together and placed in a sterile container for transport to the lab.
