For most experienced providers, the clinical distribution and the history are all they need to make the diagnosis. The skin burrows are not easily visualized and neither are the mites or their eggs. However, sometimes because the history is not straightforward or because of the presence of complications or to convince the family of the validity of this clinical diagnosis, the provider may order a skin scraping test where the mites, larvae, eggs or feces are seen in the scrapings. If the lesions are nodular, a skin biopsy may be warranted. Other tests include using adhesive tape and then viewing it under a microscope or using dermoscopy (specialized dermatologist equipment).
