Abstract

49 sera from patients with food allergies confirmed by challenge, and 26 with suspected ones were assayed with the DPC AlaSTAT liquid phase EIA, and the Phadebas RAST CAP RIA. 22 foods were tested (4 animals, 18 vegetables). Controls were performed on non-atopics (N = 8) and atopics (N = 8). Specificity was 100 %. Sensitivity was 76 % (animals) and 73 % (vegetables) (87 % for prick-tests, 76 % for RAST). Concordance RAST CAP/AlaSTAT was 79.6 % ; prick-tests/AlaSTAT : 76 % ; prick-tests/RAST CAP : 73.9 %. AlaSTAT detected specific IgE even in sera with low total IgE (<60 KU/l), while RAST CAP was inconclusive. Dilution studies and reproductibility were excellent. AlaSTAT EIA compares favorably with the Phadebas RAST CAP RIA for measurement of food specific IgE antibodies. © 1992 Published by Elsevier Masson SAS.
