(D1) and Dermatophagoides farinae (D2) are the most commonly seen mites in our country (3).
Reports of patients with an inhalant allergen panel were reviewed and those positive for HDM allergies (Dermatophagoides pteronyssinus
[DP] and Dermatophagoides farinae [DF]) were included for this study.
Allergic rhinitis (AR) is a mild-to-moderate allergic disease affecting approximately 10% to 30% of the population worldwide. House dust mite (HDM) is one of the most common AR allergens in the world, and the most common species are Dermatophagoides pteronyssinus
and Dermatophagoides farinae .
The allergens were Blomia tropicalis (storage/house dust mite), Dermatophagoides pteronyssinus
(house dust mite), Dermatophagoides farinae (house dust mite), Felis domesticus (cat), chicken meat, shrimp, egg white, egg yolk, cow's milk, peanut, Apis millefera (honey bee).
The allergens used included plants (trees, pine, verdure, grass, cereal, weed and olive), fungal spores (mixture of Alternaria, Cladosporium, Penicillium, Aspergillus), mites (Dermatophagoides pteronyssinus
, Dermatophagoides farinae), and animal epithelium (cat, dog, bird).

House dust mites (HDM), particularly Dermatophagoides farinae (Der f) and Dermatophagoides pteronyssinus
(Der p), are responsible for sensitization of more than 50% of allergic patients worldwide (1,2).
(4) The positive predictive value for Dermatophagoides pteronyssinus
ranges from 29% to 43%.

This testing either is a skin prick or blood test for the two main species of dust mites: Dermatophagoides pteronyssinus
and Dermatophagoides farina.
