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.
