Secondary Assay for Greater Confidence
The Assurance® GDS EHEC ID E. coli O157:H7 Tq 4-channel multiplex assay is designed to follow the Assurance® GDS E. coli O157:H7 Tq assay. Potential positive enriched samples from the first assay can be genetically confirmed as containing E. coli O157:H7 per the revised USDA FSIS definition (including stx1, stx2, and fliC:H7 genes).Additionally, the GDS EHEC ID assay can also be used to confirm isolated colonies from presumptive positive samples for E. coli O157:H7 as part of the cultural confirmation.
Results are available the same day when using the complete Assurance® GDS EHEC method, saving precious time for your perishable food samples.
