Detection and Inhibition of IgE for cross‐reactive carbohydrate determinants evident in an enzyme‐linked immunosorbent assay for detection of allergen‐specific IgE in the sera of dogs and cats

Veterinary Dermatology, Volume 31, Issue 6, Page 439-e116, December 2020., 2020
Background It has been demonstrated recently that immunoglobulin (Ig)E specific for cross‐reactive carbohydrate determinants (CCD) is present in the serum of allergen‐sensitized dogs and cats, and that these CCD‐specific antibodies might confound serological testing. Hypothesis/Objective The objective was to document the prevalence of CCD detectable in
