Abstract
Serological assays for latex (LAT)-.specific IgE antibody are extensively used in the diagnosis of LAT allergy. We present the results of testing sera with two FDA 51OK cleared, LAT IgE kits (CAP System and AlaSTAT Microplate [ALA]). Total IgE levels were also measured. The sera were obtained from 381 workers employed in numerous, non-healthcare industries over the last ten years and stored frozen. Twenty-six sera gave positive (pos) results using the ALA assay (6.82%), while 24 yielded pos results (6.30%), using the CAP assay (pos cutoff= about 0.35 kIU(A/L). The assays agreed on the pos or negative (neg) status of 349 samples (91.6%). Discordant results (ALA pos, CAP neg) occurred in 17 sera (4.46%), while ALA neg, CAP pos results occurred in 15 sera (3.94%). Both assays agreed on the pos status of 9 sera (2.360/0). The mean total IgE of all sera (N=374) was 144.19 +/- 284.00 kU/L (+/- SD). There were no significant differences (P=NS) between the mean ALA and CAP assays' measurements of LAT antibodies for all 381 participants, yielding 0.28 +/- 0.19 and 0.34+/- 0.59 kIUA/L, respectively. CAP and ALA results were significantly correlated, (0.271, P
