House dust mite Dermatophagoides farinae, d2

House dust mites (HDM) are the most important causes of allergic sensitization and allergic diseases, including Dermatophagoides farinae as one of the major species. Mites are dominant in temperate environments, damp and humid dwellings.

HDM fecal pellets are reported to be a major source of allergens that cause allergic reactions after inhalation.

Mite allergens can cause symptoms in sensitized humans by inhalation, ingestion, and direct contact.

A high degree of cross-reactivity has been noted between extracts of D. pteronyssinus and D. farinae, a high degree of cross-reactivity was observed, whereas reactivity between Dermatophagoides and Blomia tropicalis was limited. Tropomyosins play an important role in cross-reactivity. Tropomyosin allergens from HDM have been reported to cross-react with crustaceans (shrimp, lobsters, crabs, crayfish) and mollusks (mussels, oysters, scallops, clams, abalone, snails, squid, octopus, cuttlefish).

Determination of specific IgE in human blood to House dust mite Dermatophagoides farinae, d2, shows the body's reaction to this allergen.

Test method is ImmunoCAP (Immunofluorescence on solid phase).

Units of measurement is kU/l

The sampling biomaterial is venous blood

Preparation for the analysis: it should be taken on an empty stomach, do not smoke for 30 minutes before the analysis
