The Assurance® GDS system is a proven molecular platform comprising three simple steps: sample enrichment, sample preparation assays, and PCR analysis with the Assurance® GDS Rotor-Gene®. Designed for optimum flexibility, various portions of the Assurance® GDS sample preparation can now be automated allowing industrial and plant laboratories to customize their testing to better fit their changing needs.
Assurance® GDS utilizes proprietary magnetic particles and a unique concentration device (Assurance® GDS PickPen™) to capture target pathogens from an enriched sample, separating the target from inhibitory background materials and ensuring valid PCR reactions for all sample matrices. While other molecular methods rely on sensitivity compromising dilution protocols to prevent failed reactions, PickPen™ IMS technology improves assay sensitivity and detection by concentrating pathogens, removing the risk associated with matrix variability and increasing user confidence in test results.
Results are available same day or next day, instead of following a multi-day full cultural confirmation, saving precious time for perishable samples. The Assurance® GDS pathogen detection system includes assays for Salmonella, Salmonella HET, E. coli O157:H7, Shiga Toxigenic E. coli (STEC), Shiga Toxin Genes, Listeria spp., Listeria monocytogenes, and Cronobacter. The system has been validated by a variety of third parties including AOAC, AFNOR, MicroVal, and Health Canada.
