In the present work two commercially available immunoassays for allergen-specific IgG4 detection were compared, IgG4 FAST Test and ALLERBLOCK-MS IgG4 EIA Kit. For this purpose 30 serum samples were tested for IgG4 antibodies (Abs) specific to Dermatophagoides pteronyssinus (Dp) by the two immunoassays. Eleven serum samples were collected from normal subjects, 6 from Dp-atopic patients never treated by specific immunotherapy (ITS) and 13 from Dp-atopic patients previously treated by ITS. Pearson's linear correlation analysis showed a significant correlation of results from the two immunoassays. However, a better discrimination of Dp-specific IgG4 values between ITS-treated and untreated patients or normal subjects was obtained by FAST than ALLERBLOCK-MS method; moreover, the former showed a better intra-assay coefficient of variation than the latter.

Sera of sixteen horses with clinical signs of EIA from six different outbreaks and sera of 100 uninfected horses were used to validate an ELISA for EIA diagnosis. The antigen used was a recombinant protein derived from the amino-terminal portion of the transmembrane envelope protein of EIA (gp45). Reactivity between positive and negative sera could be clearly distinguished. Comparison with the traditional agar gel immunodiffusion test (commonly called the Coggins test) showed that the ELISA was superior in sensitivity. Comparison of this ELISA with the FAST-ELISA system showed that the latter was less sensitive. Although the FAST-ELISA was much faster to perform, it could not be recommended as a diagnostic test in its present form, because the margin between reactivity by a positive serum and a negative serum was not high.

Enzyme-linked immunosorbent assay (ELISA) represents a bioanalytical strategy frequently used for rapid screening of mycotoxin deoxynivalenol (DON) in cereals and derived products. Due to a considerable affinity of some anti-DON antibodies to structurally similar DON metabolites, such as DON-3-glucoside (DON-3-Glc) and 3-acetyl-DON (3-ADON), a significant overestimation of DON concentrations may occur. A validation study of six commercial DON-dedicated ELISA kits, namely Ridascreen DON, Ridascreen FAST, DON, DON EIA, AgraQuant DON Assay, Veratox 5/5, and Veratox HS was carried out on wheat, barley, and malt matrices. Performance characteristics of all tested ELISAs were determined using aqueous solutions of DON, DON-3-Glc, and 3-ADON analytical standards, further with extracts of artificially spiked blank cereals, and finally with matrix-matched standards of all three compounds. In the final phase, the accuracy of data was assessed through a comparison of DON concentrations determined by particular ELISAs and reference ultra-high-performance liquid chromatography-tandem mass spectrometry method. For this purpose, both quality control materials and a comprehensive set of naturally and artificially contaminated samples of wheat, barley, and malt were analyzed. High cross-reactivities were proved for both DON-3-Glc and 3-ADON in the majority of examined assays, and moreover, a considerable contribution of some matrix components to overestimation of DON results was confirmed.
