Horsefly, i204

Gadflies (tabanid flies) are among the most commonly encountered blood-sucking insects worldwide, but allergies to tabanids may be underestimated because reliable identification of the biting insect is rarely possible.

Gadflies inject allergens into humans and animals through a painful bite, usually to the upper body. Local transient cutaneous reactions to a tabanid sting are common, and systemic reactions of varying severity from generalized urticaria to anaphylaxis have been reported.
Three allergenic molecules have been characterized in Tabanus spp. that cross-react to some extent with homologous proteins from wasps (Hymenoptera spp.) and mosquitoes.

Determination of specific IgE in human blood to Gadfly, i204, shows the body's reaction to this allergen.

Test method is ImmunoCAP (Immunofluorescence on solid phase) method

Units of measurement is kU/l

The sampling biomaterial is venous blood
