Method Description:
VIDAS UP Listeria is an enzyme-linked fluorescent immunoassay for the detection of Listeria using the ELFA technique (Enzyme Linked Fluorescent Assay).
Confirmation services also available.
Additional Information:
Based on a new phage recombinant protein technology, VIDAS Up Listeriais an automated qualitative test for the detection of Listeria in human food products and production environmental samples. Note that a percentage of all raw commodities may contain a low level of these organisms.
PCR and ELFA Method Comparison – Which method should I choose?
Both test methods will provide accurate results. See the table below for a high-level test comparison.
| Assay | What does this test measure? | Test Advantage | |
| PCR GENE-UP® | Molecular Assay | Detects pathogens using target sections of DNA that are specific to that pathogen, making the assay more sensitive than the VIDAS. | Fewer false negatives and fewer false positives. |
| ELFA VIDAS | Immunoassay | Detects pathogens by having proteins bind to pathogen-specific receptors. | More cost effective. |
