This proposal combines multiple competitive ELISA assays with different cross-reactivity profiles and multivariate data analysis techniques. Data have been analyzed by principal component analysis in conjunction with a novel K-nearest line classifier. This proposal allows simultaneous detection of up to four different steroids in the range of concentration from 0.1 to 316.2 nM with a total rate of 90.6% of correct detection, even in the presence of cross-reactivities. A methodology for concentration prediction is also presented with satisfactory results.8 p.application/pdfeng(c) Calvo, Daniel et al., 2011Enzimoimmunoassaig sobre fase sòlidaEsteroidesAndrògensEnzyme-linked immunosorbent assaySteroidsAndrogensinfo:eu-repo/semantics/article6073482022-09-01info:eu-repo/semantics/openAccess21826310
