<unk>  (CCDs) play a role in the context of allergy diagnosis. The terms CCD or CCDs describe protein-linked carbohydrate structures responsible for the phenomenon of<unk> -reactivity of sera from allergic patients towards a wide range of allergens from plants and insects. In serum-based allergy diagnosis, antibodies of the IgE class directed against CCDs therefore give the impression of polysensitization. Anti-CCD IgE, however, does not seem to elicit clinical symptoms. Diagnostic results caused by CCDs are therefore regarded as false positives.
