Demodex – PCR

deep skin scraping

realtime PCR (semi-quantitative)

1 - 3 days

• Since demodex mites belong to the normal skin fauna and only an excessive increase leads to demodicosis, a positive PCR result should always be interpreted in connection with clinical and epidemiological data. A negative PCR result cannot completely rule out an infection.
• If reduced immunocompetence or immunodeficiency is suspected, examination of the lymphocyte subpopulation by flow cytometry may be helpful.
