Read across approach toxicology

WebMar 27, 2024 · We developed Generalized Read-Across (GenRA) ( Shah et al., 2016) for automated read-across prediction of a property of a chemical (called the target) as a similarity weighted average of the same property from analogues (also referred to as source analogues) ( Low et al., 2013 ). WebRead-across has generated much attention since it may be used as an alternative approach for addressing the information requirements under regulatory programmes, notably the EU's REACH regulation.
