421412 Allergy TWELVE
AESKUBLOTS Allergy TWELVE is a membrane-based enzyme immunoassay for quantitative detection of IgE-antibodies against multiple allergens and total IgE in human serum and plasma. Antigens are positioned in parallel lines at exactly defined positions on a nitrocellulose membrane.
This assay is a tool in differential diagnosis of Type I hypersensitivity (allergy).

* Cross-reactive carbohydrate determinants (CCD) are protein linked carbohydrate structures present in a wide range of allergens from plants, pollen, mollusks, and insects. IgE antibodies against CCD are present in 25% of patients suffering from allergic symptoms. IgE antibodies against CCD give rise to the impression of polysensitization. Anti-CCD IgE antibodies are not allergen-specific and do not seem to be correlated with clinical symptoms. Multiple positive results in combination with a positive CCD result should be interpreted carefully, and false-positive results due to anti-CCD IgE antibodies should be considered.
