Comparison of Guinea Pig IgE Antibodies Estimated by ELISA with Those Estimated by Passive Cutaneous Anaphylaxis

Guinea pig IgE antibodies to ovalbumin or mite were measured by enzyme-linked immunosorbent assay (ELISA), and the levels of IgE antibodies to mite were compared with titers of passive cutaneous anaphylaxis (PCA). The results of ELISA were highly reproducible when the assays were done in the same microtiter plate and on the same day. The levels of IgE antibodies to mite determined by ELISA correlated well with the PCA titers (n = 29, r = 0.70, p
