Multidetection Of Anabolic Androgenic Steroids Using Immunoarrays and Pattern Recognition Techniques

A first step towards the multidetection of anabolic androgenic steroids by Enzyme‐linked immunosorbent assays (ELISA) has been performed in this study. This proposal combines an array of classical ELISA assays with different selectivities and multivariate data analysis techniques. Data has been analyzed by principal component analysis in conjunction with a k‐nearest line classifier has been used. This proposal allows to detect simultaneously four different compounds in the range of concentration from 10−1.5 to 103 mM with a total rate of 90.6% of correct detection.
