Additional information
VIDAS Listeria monocytogenes Xpress (LMX) is an enzyme immunoassay for the detection of Listeria monocytogenes antigens using the ELFA method (Enzyme Linked Fluorescent Assay). Note that a percentage of all raw commodities may contain an inherent 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. |
Common Listeria monocytogenes 25g and Environmental swab (ELFA) Test Testing Questions
While our sales and customer service team are happy to answer general testing questions, consultations typically start at a rate of $250 per 30 minutes regarding the interpretation of reported test results or questions about our test methods. We cannot consult on regulations, tolerance limits, or claims.

Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
