The SureScan Dx microarray scanner is indicated for use in a clinical laboratory environment when measuring fluorescence signals of labeled DNA or RNA targets hybridized to microarrays used as part of a validated diagnostic assay. The system has been validated for use with comparative genomic hybridization and gene expression microarrays. The SureScan Dx microarray scanner can deliver high sensitivity and resolution for copy-number change analysis, as well as broad dynamic range.
