Abstract: The purpose of this study was to document the continued reproducibility of results yielded in different laboratories that perform a monoclonal antibody cocktail-based enzyme-linked immunosorbent assay (macELISA) for detection of allergen specific immunoglobulin IgE in companion animals.Replicate samples of 21 different sera pools were independently evaluated in a single blinded fashion by each of 10 different technicians functioning in 8 different laboratories.For evaluations completed by multiple operators, the average inter-operator variance was calculated to be 7.1% (range = 3.4-10.7%).The average intra-assay variance among reactive assay calibrators in all laboratories was 4.6% (range = 1.6-11.5%).The overall inter-assay inter-laboratory variance evident with reactive calibrators was consistent among laboratories and averaged 12.1% (range 11.2-13.4%).All laboratories yielded similar profiles and magnitudes of responses for replicate unknown samples; dose response profiles observed in each of the laboratories were indistinguishable.Correlation of optical density values observed for individual allergens between and among all laboratories was strong (r > 0.90, p < 0.001) and concordance of results across the entire spectrum of responses exceeded 95%.Collectively, the results demonstrate that the macELISA for measuring allergen specific canine IgE is robust and continues to yield reproducible and consistent results among different operators and between laboratories using the assay.
