The three newly developed sandwich assays were calculated with reference to baker's yeast as the standard. The floor dust in the inhibition EIA was calculated with reference to laminarin as the standard, the BGFA EIA was calculated with reference to CM-curdlan, and the EHSRC was calculated with reference to scleroglucan. n/N, number of samples with a result greater than the LOD/total number of samples.
