Scabies is the parasitic infestation of human skin by the mite Sarcoptes scabiei (L.) (Sarcoptiformes: Sarcoptidae). Its clinical manifestations resemble those of numerous other skin diseases; therefore, its definite diagnosis is based on the detection of S. scabiei by a clinical laboratory. Even though various assays have been developed such as epiluminescence microscopy, enzyme-linked immunosorbent assay, and real-time quantitative polymerase chain reaction (Wong et al., 2015), the microscopic examination of skin scrapings remains the gold standard for diagnosis as well as the least expensive choice.

Skin scrapings are routinely sent to laboratories for a potassium hydroxide (KOH) mount report looking for both fungi and mites. The overall rates of misdiagnosis, however, have been reported to be up to 45% (Anderson and Strowd, 2017). False negative results could be attributed to lack of experience by microbiologists and to the immobilizing...
